500 HP evosport C32..... (EuroTuner GP Day 1)
lol yeah how much money to get that power??? ~$10,000??
There must be something different with the tolerances of early production C32 vs 2003's, or mine is quite off. It would be impossible for me to run 245's up front on my 8.5" ET32 wheels without rubbing on the strut tube and having additional fender clearance issues, although the fender rolling eliminated the problem for 235's.
Running a coilover strut reduces the inside clearance by about 2mm depending on manufacturer. The typical Sachs strut is a 55mm diameter with a 5mm reduction indent at the intersection of the wheel rim/tire bead contact point. If the H&R coilover is an inverted monotube design, then it should be similar to the Bilstein coilover strut and have a continuous 52/53mm strut housing diameter. This additional reduction of 2/3mm at the point of contact is the difference between rubbing or not rubbing the inside of the strut tube depending on tire manufacturer in the same section widths. The RA's 30mm offset will offer an additional 2mm of inside clearance while reducing outside/fender clearance by the same 2mm. If running stock ride height, the 30mm is fine, but lowered below 13.5" lip to hub center, the clearance becomes important.
So comparing my car, the RA's will offer an additional 2mm of inside clearance, but the section width difference between 235's and 245's is 10mm, or 5mm per side. I come up short 3mm, unless I run a tire who's 245 tread width is the same as another tires 235 tread width. Rosso's would fit this category. It is cutting it very tight with the coilovers providing an additional hurdle to jump over. The rear problem for me would be having an additional 5mm of tire towards the outside. I only had the rubbing problem on one side of the car. And have never experienced rear rubbing problems with 9.5" ET36 wheels with 265's in back at a ride height of as low as 12.5", which many others have experienced.
On the track, the extra outside increase in width would not cause much problems since most tracks are very smooth and the suspension travel is usually lower at these venues than on the street. In addition, steering angles are less.
I can see why a spacer is not needed for the caliper, but 245's seem almost impossible, which is a shame because the car really needs extra rubber up front. Congratulations on fitting the 245's on the front without any issues. You are very lucky. I may just have to buy a wheel and see for myself!
What track are you running in the competition? Good luck.

We were seriously out-matched on the track. The cars ahead of us were all very set-up. The avalon car spent all day on Monday doing practive and track set-up and had full Ohlins Race Dampers. The RS4 was supported by Eibach had they were doing spring changes to improve the car during the day. Not to make excuses, just to reaffirm that we are very proud of the C32 to be so close. This is a VERY tight track, and if we had a diff and camber, we would have been sub 1:30.
Overall we are VERY happy. We were top three against some impressive cars and the top three stole the show!
We also did skid-pad and expect to see some awesome pics from that in the article!
Thanks!

Thank you for waiting.

Thanks

Not give excuses, but here are several factors that affected our times:
1. Bad track - bumpy at the end, hot 100F day with 125F track temperatures. Head-on wind that came in afternoon slowed everyone down by 0.2 - 0.3 secs.
2. Stock heat exchanger could not handle boost and hot ambient temperatures. At the end of the run DME would pull out 5-6 degrees of timing as Air Charge Temperatures would get over 170F. This is why Stage III is in development - bigger exchanger will be part of the it. This is also why we had 113MPH ET speed vs. 117MPH it should of been for 400HP at the wheels.
3. Tires - we had to use Dunlop Road racing tire for both drags and road events. It had to be the same tire, as in - if you destoy it at drags you can not do road event. So we were conservative and tried not to destroy the tires with burnouts. Besides this is not tire to use for drags, the side walls are way too stiff.
4. RS4 that won the event runs mid11s at 118-119 on East Coast tracks, the best it could do was 12.1 at 115.
Shortly we will retest on a better track and will post the times.
Last year, at Euro Tuner GP, we ran E46 M3 on the big track at Willow. 2.2 miles vs. 1.2 miles (?). We won with 1.31. Next car was 1.37. But there were no drags last year.
My guess E46 M3 would of been around 1.30s.
