how wide are your wheels?

bassn_07

Prodigymb, I might be selling my Kosies. They are 18x9 with MT's 265-40-18's and have only been used once at Famoso. Not quite sure yet but I've contemplating on whether or not to get the CCW's but the price is a little high.

I've had great experiences with the OEM rims on BFG drag radials and 16" CCW Classics with Mickey T's. Neither one is advisable for wet areas...fish tailing with any aggressive throttle blips...

prodigymb

I am convinced on the Mickeys !! I just don't want to spend a 1000 bucks on CCWs... and trying to find a cheaper alternative.
What about the 275/40/17 Mickey ET Radial? Can that be squeeze onto a 17x8.5 wheel? If so these may work.....or may work with a small spacer although i doubt it because my OEM 18" CLS wheels with offset 37 have ALOT of clearance/spacing between the rear brakes.

just a side note..
tire rack says rim width should be 9-11" for 275/40/17 and 7-9" for 255/50/16. i used the spec for the BFG drag radial since they don't carry MT

I can attest to the MT ET Street Radials. They're the DR to get if you can find a wheel/tire combo that works. Of course, some slicks or cheater slicks would be even better.

The Hoosiers are much lighter there is no doubt about it. As long as you do a long burn out there will be no wheel spin off the line.

The big difference other than the weight of the tires is the PSI you need to hook up well. With the Hoosiers i had to run about 14-17psi to get them to hook. The MT's I run at about 24psi (I think?) So what I noticed was with the Hoosiers I would get a CEL for incorrect gear ratio.

I attributed this to the amount of tire expansion I would get when the car picks up speed on the track from low PSI and lack of steel belts. The results in ET's were still in the 11's but my traps were lower and in the 113mph range.

I switched to MT's only because I had a set in my garage. Right off the bat I noticed my burnouts were easier to do. The higher PSI in the tire made it easier for the other tire to start spinning when I started my burnout.

My traps with the MT's were in the 117mph range. So the 10psi difference in tire pressure from the Hoosiers to the MT's was paying off in trap speed. Also the Smoky burnouts were letting me hook up really well because i was able to get both tires spinning (No LSD) for a longer time with the MT's

Also I noticed the Hoosiers can cause wobble at the top of the track.

7.5 inches they fit a 255 no problem.

IF a 35 offset will fit on the rear

search at tire rack under a 1999-2000 C230 and go with 16 inch wheels they are light. Lots of us are running 255's and hammering some good times with this wheel/tire combo.

Chiromikey (E55) 255/50/16 = low low 11's
Hooleyboy (me, C55) 255/50/16 = 11.75
Curzinquick (Srt-6) 255/50/16 = bracket racing master in the 11's

the 255/50/16 is capable of hitting the 1/4 time you are after.

prodigymb

yeah tire rack says that to fit a 255/50/16 the rim should be 7-9" wide. 7.5 is on the low side but if works - great. i found a wheel on the rack thats 16x7.5 and it' 99$ weighing 20 lbs. Can you post a link to the wheel you used?

I've done both. Didn't experience a noticeable difference in times although dyno mode should produce marginally faster times.

Maybe. The potential issues are caliper clearance, offset, and wheel bolts.

For wheel bolts you'd need a special 14x1.5 mm bolt with an R12 ball seat. R129s use a 12x1.5mm bolt with an R12 ball seat while a W211 uses a 14x1.5mm bolt with an R14 ball seat. RAD sells 14x1.5mm bolts with an R12 ball seat: http://www.radusadirect.com/c=IvLx21...lts.ball_seat/

wheels from tire rack look like a better idea. question becomes whther they will clear the calipers in the rear..... i think they are worth trying.

hooleyboy

I was just going to send you that link for those wheels LOL. I use those wheels and they work great. If you beat them up with the Lug nuts its no big deal.

bassn_07

Prodigy, could you make some room in your mailbox.

prodigymb

just did


thanks hooley. i think at a 100$ it's worth trying.....worst comes to worst i can return them and lose shipping $.

^ Once you mount tires on the weheels I doubt they will take them back

Interesting. You are running too much pressure in the MT's actually. They recommend runnind 12-16PSI at the track for those sizes. I think I'm right at about 18PSI when I run mine and they dead hook! I've never even chirped them at the track. I was able to cut 1.52 60's like that. When you do a burnout make sure you go through the water box and do a quick spin in the water. This will help you spin both tires and heat both of them while doing a burnout (LSD makes sure both spin).

prodigymb

i'm not gonna mount the tires. i know the tire will fit. i am going to test fit the rim to make sure it clears the caliper.

^^ When you hitting the track?

prodigymb

going tonight to Atco. DA 36ft right now.

prodigymb

Went to ATCO last night and it was horrible. Got there about 7PM and only got one run in at 10:15PM or so......one car spilled oil all the way down the track and return road too and it took them 2.5 hours to clean and another car broke immediately after, and then another car spilled oil.......but I wasn't gonna leave hehe.

I wasn't sure what pressure to run in my 305/35/18 Nitto DRs, so I dropped it down to 21PSI. Did a fairly long burn out to get the Nittos to sound warm. Since I knew it was going to be my only run I did not launch as hard as I could have, because I didn't know if the Nittos would spin. Cut a 1.80 60' which is my personal best ( previous being a 1.84-1.86 on street tires). I also ran my best time to date of 11.6@120

Nittos were great, did not spin, did not hop, and can def do better then a 1.8 ......I just didn't know how hard I could leave off the line. They did not rub on launch or when the car is raised at all......they did rub on the outside a bit when the car lowered ( my car is lowered on adjustable links to "no wheel gap")

I would say that for stock height vehicles this setup is great, and I don't mind the rub much either on my lowered car. I will be throwing these up in the classifieds since they are still practically new so that I could get as much money back as possible to put towards my 16" setup.....if noone grabs them by next week I will try to go the track again and hopefully get more then one run in.

- Great Job for only getting in one run with new tires! I'm sure once you get a few more runs in you'll drop that ET with no problems. How was the weather?

bassn_07

Wow! You guys have it good during this time of the year with conditions being as good as they are. I checked and DA during your run was -1000 . If I were you I would get back out there before the weather starts warming up and break your PB again .

Unfortunately the good weather days have passed here but when fall comes I'm sure the west coast cars will have a chance at breaking records at FAMOSO!

prodigymb

Thanks Alan. Yeah DA was -780 at time of my run which is nice.

I am kinda concerned with my trap speed at this point as well because 120.1 is a bit low for my mods - i think.

-80MM AMG TB
-Evosport 175MM Pulley Set
-Evosport Phenolic Spacers
-Evosport Ceramic Coated Headers
-LET Custom Ecu (Dyno Tuned)
-K&N Filters
-CM30 Pump
-Code 3 Heat Exchanger
-No secondary cats, no resonator
-New supercharger clutch and backing pulley
-New trans and new oem torque converter
-305/35/18 Nitto 555 Drag Radials

bassn_07

Yeah, now that I see your mods the trap speeds do look low. Earlier this year at Sacramento I ran a 11.5 with the VR600 using street tires with a trap of 124 (Toyo T1R's). I had very similar DA as you, I think I was right around -450 or so. By chance did you have a slight head wind or anything?

Do you have a LET custom tune? When I ran the 124 trap speed I was using VRP's box tune. I now have LET's custom tune and today I'm hitting the track...we'll see. I know have more mods then before so I should see a improvement but the DA is going to be crap. If I coud squeeze one run right at closing time the DA should be around +500-+700. I'll hope for the best and see how she does.

Either way nice ET!

prodigymb

I am not 100% up to speed on VRP packages.....VR600 is pulley, tune, 80mm, headers, cams right? I do have a LET custom tune with headers

I am not sure about the wind to be honest with you it was 10pm and I just wanted to get out of there after 3 hours of waiting.

bassn_07

The VR600 is with no cams. I basically have the same thing as you except I had the stock mid pipes with all cats and resonator. I just noticed that you have the LET custom dyno tune...hmmm. I just had the newest tune installed from Vadim and it was running very lean, good thing I only had it on for a week or so ! I know have LET's custom dyno tune and it made the almost the same power but at much safer AFR.

I really don't know why your trap speeds are on the lower end for your mods. Maybe some of the more experience veterans or even LET could jump in give their input. The thing that gets me as that you had good conditions . I'll see tonight but even at +1500 DA my car still trapped 122 with my old VR600 box tune. Tonight I'll have similar conditions as Famoso which should give me a comparison...depending on track prep. VR600 tune vs. my new LET tune. BTW...I have a few more mods since Famoso so I should do much better, in my mind. Anything less will be dissapointing.
