Did you have a problem with Ate Blue? I've used it in my A6, C32 and 944 without any problems.

PS: I just swapped my street pads back into my 944 and noticed a broken dust gasket on the ONE piston on my front brakes. I look online for a rebuild kit and find one at Paragon parts for $12. I also need to refresh the clips and pins ($40). So for about $50 I can rebuild each caliper. Then I see rebuilt calipers with all new hardware for $49!!! Duh! Who said owning a Porschuh was expensive?

 

Ate blue or gold is OK motul 600 for the price is a steal. I remembered hearing a rumor that ATE was getting pulled for some reason or another years back. I originally ran it, then I used to use SRF with my 14" kit so I didn't have to change it as much but 600 is damn close.

ON the benzo, I have a set of re-01r's and they are a huge improvement over ps2's or anything in that max category. The new pirelli p zero's were dubbed by tire rack as extreme but they have subsequently been downgraded and have no rankings! What BS!!

The re-01r's are also 120/180 tread rated so although not super close to a cup tire at 80ish they're not going to last all that long if a DD. These tires remind me a lot of my bfg kd's I had on my 996 when I would track it with pss9's and gt3 bars. Great compromise if you only want to run 1 set street/track. However that said, the KD's NEED to be run really low to be good or they're greasy, and they like to cup e.g. feather. I remember something like 27 hot but that's Porsche front iwith -2f so dunno benzo.

I have notes somewhere on all that setup crap. Tires make a huge difference and as they're consumable - I've gone through 4 sets at 35k on the benz- get something you'll really be happy with even if it doesn't last quite as long. I remembered the contis that came on the car. I hated them so much! I corded them at 5 mo!

 

I absolutely hated the ContiSport2s as well. I am continually amazed when I read car reviews where a car is tested with this tire (obviously full-tread) and the review is positive. Maybe they perform differently in different sizes. I was terribly disappointed in the lack of grip. Not a shock when you look at the tread pattern and realize that 1/2 the tread area is groove. Not much rubber.

 

I would bet that when any car testing is done it's always done with michelins or pirellis and NEVER with contis! They are sooo terrible and it always made me laugh seeing them on a Porsche as stock or anything that's about handling. I was going to have them swap them when I bought the car from the dealer as they were new but didn't want to wait or deal with the hassle.

The most amazing thing is that you'd think they'd last better being so hard. Nope the lack of traction just made me light them up half a dozen times a day. The new re01-r's once warm don't spin! Yeay

 

i ran ate blue for a few events but when i switched to full dot r compound (hankook z214) i started boiling it. 1st event -pocono north in may- boiled it, came in let it cool, boiled it again in short order. did a quick bleed and same result after a few laps. thought my day was done but someone had a few bottles of 600 and assured me that will take care of my prob. so i used my turkey baster to suck as much ate out of the resevior as possible replacing with the 600. pumped it through - ended up with green fluid prob a 80/20 mix of ate/600 but was able to run hard all day (open track)

a buddy of mine uses ate in his b16 honda but that's a lightweight car.

 

correct- the abrasion due to slippage will rub out the rubber quickly. i was amazed that the very sticky z214 lasted longer than the yoke a048s.

i like the bridgestones, have the older s-01 on the ferrari, had s-02 on my s2000 and had s-03 on my 3000 gt vr4. if the re-01s were made 235/35-19 and 265/30-19 i would have absolutely bought them over the PS2.

mitchelins ps2 SUCK for track days. maybe you guys aren't pushing. my buddy with the c55 and i had the same prob. granted they have grip but the sidewall is too soft and rolls under.

 

depends on which porschuh! my friend with gt3 already had to replace front rotors (steel not pccb) due to severe cracking. think he did 7-8 events. i believe they were $1200. ouch.

 

No doubt. The ***-dragger Porsches are an entirely different animal. The 944 (non-turbo) requires a lot of attention, but a little DIY skill goes a long way. As they say, "If an old Porsche isn't leaking oil, it's probably empty."

 

? Gone are those days of dripping oil, although they had to make what, 8 different replacement rear main seals to finally get it right! haha.

 

Definitely look into Bridgestone RE01R or Advan Neova for track/street tires!

Our cars are heavy so make sure you take care of your brake system before going. I think the fastest tire for the buck is the RE01R - they last quite long and is very consistent.

RT615 is gone after 1 1/2 laps....Neova is too expensive...everything else just dont' measure up.

 

Areed. FYI, the prob was that the advan neova wasn't in my size f&R that's why I went re-o1r

 

neovas are bloody expensive but available in 235/40-18 and 265/35-18 which ought to be the perfect compromise for performance and looks.

 

235's are wayyy too big for a 7.5" rim and so are 265's on an 8.5 and will make it handle like crap.

 

Thanks for the replies so far guys

 

not completely true. the higher the profile the narrower the minimum spec rim. the yoke dot r compound A048 235/45-17 works on widths 7.5 to 9 inches.

my first 6 track days were run with this very tire size on the stock 7.5" fronts. no handling problems.

 

I am only talking about 18's. and on my Porsche even on 8's 235's are sloppy and mis-sized for fronts. Look on tire racks charts for the profile of the tire and the rim size rec's- Just because they work doesn't mean they work well.

The gt3 runs a 235 on an 8.5 for a reason. First a 7.5 is a bit narrow for a 225/40/18 as I had stock on my first Porsche. I then went to 8's with the same size and-huge difference- great. Went 235 on 8- complete garbage and sloppy. I then went 235 with 8.5 and great again.

I dont' even bother joking about tracking a benz as it's too much of a joke. I wouldn't waste my time.

 

Hey there OPM WHAT THE PRICE ON THE USED TIRES YOU MENTIONED.....PM me if you prefer.

 

Hey really appreciate the advise but unfortunately I only own this Benz so have no choice but to track it. I really enjoyed the quarter runs so far and really want to find out how well can I and car do on the track

 

$200 + shipping from 02453

 

when you changed tires sizes did you stay with the identical tire? any changes lends variability which destroys any useful conclusions.

I understand what you're trying to say but i don't think the difference is night and day as you suggest. pintching tires is a pretty common practise. didn't GRM recently test a bunch of 285/30-18s mounted on 8" rims. (the R1 did not work)

my ferrari f355 runs 225/40-18 on 7.5" rims up front. are you saying this is compromised? why would they do this?

a friend of mine who tracked his c55 and now has a 997 gt3 will wholeheartedly disagree with you on your last statement. he's an instructor and was just invited by farnbacher loles to go test at VIR.

last 3 pca days i spectated i noted i could run faster laps than >75% of the cars on track. but, hey- give me a milk truck and i would still have fun so who cares......

 

I knew the post would fan the flame chalk it to a nice wine. I have real race race cars so, I should have made that caveat. Most people playing race car driver have little to no training or simply are poor drivers, so passing an enzo, gt3 or whatever in a c55 doesn't mean much to me, but I hear you and it's fun nonetheless. I have done numerous schools and events so again I have a skewed perspective- that's all. I'm also a better driver than most - my frist professional school I beat every driver and the instruction when I was 17. Everyone should have fun, but street cars are street cars so whatever.

Now onto the tire sizing. Yes the tire sizes and profiles remained the same so certis paribus my observations are relevant to you with a 225/40/18 and then 235/40/18. Well, Porsche came out with the 7.5 with a 225 for 996's from 99-01. Then in 02 they came out with the 5 spokes which are 8's with the same tire. I switched to those after going through a BBS fiasco with 8.5's and my pss9's and gt3 bars and gt3 oem mk1 rims, blah blah blah, but I digress.

In any event, there was a huge difference going from 7.5 to 8's with a 225. Thinking more was better I then tried to mimic the gt3 width but without the 8.5's as the BBS re's were. The result was that turn in suffered; it was very sloppy and handled much worse, and it was more dangerous at the limit as corrections would upset the car. It was like driving a car with 10lbs out of each tire- that's how it felt to me. ugh.

Another thing is since your talking about the F car. What are the rears and what are you running there? With the P car they're 10's with 285's. Messing with the ratio also will change things as well and it was much better with 8/10 than 7.5/10 with the same tires I have tried to get my father to do this with some of his cars but he likes to screw around with stuff and have HUGE rears like 355's or something silly on too small of a rim! I don't think he cares anymore or something

 

how come you didn't / don't pursue your talents on a higher level? i would.

f car has stock tire sizes- 225 on 7.5 and 265 on 10. tires are oem expedia s01s. some guys on the F boards put 295/35 i've posted more than once that the expedia has a sq sidewall and the 265 has a contact patch larger than most all 295s....anyway....

i'm sorry but i'm a humble wanna be racer so i will take my kicks in c32 whenever i go faster than another wanna be racer driving a 911 or whatever fancy proper sports car....

next yr, now that i have -ve camber i intend to try cups sports as i don't want the hassle of changing tires and pads at the track. i can go 18x8, 18x9 with 235/40, 265/35.or go 19x8.5 and 19x 9.5 with 235/35 and 265/30......which would you chose?

 

I could have but I'm sticking to law.

If you're set on doing 235/265 8.5/9.5 is the best bet and is what the slk55 black runs. Make sure you do the right offset though so you don't have bumpsteer.

265 is very narrow on a 10. 285 is ideal on a 10. 295 also works but is a little sloppy.

The 911 was my daily driver; I have real race cars for the track.

 

I saw that article. I think what they proved was that you were rim-limited (as in a race class limited to OEM wheels) you CAN improve by pinching wider tires onto the narrow rims. But that is if you're stuck with narrow wheels. I suspect it's always better to have wider wheels to keep the sidewalls under control.

(I don't own any race cars, and consider myself a knowledgeable but not great driver. But I stayed in a Holiday Inn Express last night...)

 

its ok dude i heard you the first time.

thanks for the advice.

fifth, you're too funny.
