Went to Atco on Tuesday and ran 11.54, 11.61, 11.61 and I was like WTF is going on why is the 60' still in high 1.7x range. Checked the tire pressure and it was at 23 psi (fail on using a gas station gauge to set race pressure). I dropped it down to 19.5 psi and next run went 11.44 with a 1.69 sixty and 10 minutes later went 11.45@123.4 with a 1.72 sixty. I should have thought to check the pressure earlier.

Wheels: 16x8 OEM Mercedes offset 36, with 5mm spacer -> total offset 31
Tires: 255/50/16 Mickey Thompson ET Street

No rub anywhere, even when the car is lowered. This setup worked out awesome. Grip off the line is amazing, next time hopefully I will crack 11.3 or maybe even high 11.2 if I can get the 60' down to a 1.6-1.62.

Congrats Mark!! Great times! I remember when I met you at etown last year, you said you were not modding the 55, I was like "right"... Wait till the Mod bug hits you.

Awesome tire set up.

Congrats on the PB Mark.

Keep going lower and lower and race that ******** C63 already!

See you at MIR on the 5th!

blackbenzz

Congrats!!! Thats a strong car Work on the 60' a bit more, you have more left on the table

So did you drive out there with those 16s on the back or did you put them on at the track?

Thericker

Nice work bro!! 16"s baby 16"s

novae500

nice times you got there.

Just a quick suggestion for you guy, have you ever try to use the airmatic to raise the front end when you launch the car? That'll definitely help with the short time.

aleksandar1099

Awesome times man!

Very nice set up! Where did you buy the 16s, craigslist?

prodigymb

I drove on them. They are street radials - nothing wrong with driving on them on street

prodigymb

I always launch with it raised up.. and suspension in comfort mode.

yeah i probably coulda gone faster but i wasted 3 passes not realizing the pressure was too high....

nah local guy had them on his audi. he polished the faces by hand

ZAHANMA

definitely helps. we discussed this last track day at MIR. with the airmatic suspension, putting it in comfort and with a higher ride height, it allows the car to better squat on the launch... nice!!!!

Better weight transfer, FTMFW!

BenzoBoi

Good stuff! I'm sure with a lil more practice you'll shave another tenth easy!

E55Bullet

Nice pass! What are your mods if you don't mind telling, if not it's cool!! Any idea what those wheels are off of? year and model?

bassn_07

Awseome times Mark! I'm glad the mt street raidals worked and you were able to get a new pb. Play around with the launch a little more and come back with a solid 11.2-11.3. Keep on trying what we talked about and I'm sure you'll get that 60' time lower. Onc again congrats and get back to the track!

Nice Prod, there are a few MB OEM wheels out there you just have to look for them. They may not be as light but they can still get the job done at a fraction of the cost.

thats a awesome time!!!!! good job getting ur times lower as u went. I have a question though do u think 19psi would be the right tire pressure for our stock 18in wheels on b/f goodwrench street drag radials. Or would the psi change for a larger rim size? Im also going to the track on sunday and i need to brake in to 11.5 or 11.6 or im gonna go nuts lol.

Benz-O-Rama

Great times. It's always great to beat your personal best, regardless of what that number is. You need to find me at MIR for a heads up run. Looks like you're a few ticks quicker and few mph faster than me, but maybe I can beat you on the tree.

Congrats on the new Best! Nice wheel and tire set up for your lowered ride..

With or without traction control?? (ESP)

not sure exactly what car the wehels are off of, but i know its a 211 e class. i got them off the car so i will post some part numbers....

thanks Alan - the launching technique worked. kinda glad that i didnt go as low as i can because as someone mentioned in abvoe posts - beating the personal best always feels great even if it's bya little bit.

when I ran 18" DRs i ran 23-24psi at the track and 25psi on the street. but you gotta play with it, if you feel to much spin .....keep dropping pressure 2psi at a time. i'd start at 23-24 and work down.

i'm not sure if i'm going to drive down for MIR yet. but i'd love to do a run, i have gotten reaction times as low as .004 -.008. i don't try to get a good RT unless there is an "interesting" oponent.

i turn it off .....but with these tires it wouldn't matter since there was no spin on the 11.4 runs. even if you have it off and you see it kick in even a little bit .....that should tell you that the run is not going to be clean.
well they are 16s with alot of sidewall so when they are at 19psi they feel a bit sloppy.....nothing to serious. when they are inflated normally they drive fine.
