Best Wheel for ESP
Best Wheel for ESP
I am working on preparing my Evo for ESP this year. I would like to run either 17x9+ or 18x9+ wheels with the largest Hoosiers possible. Anyone like to suggest a wheel that works well (and is light and fairly cheap)? I would like to go with 285/30-18's if possible.
Thanks for any help.

5Zigen FN01R-C, Enkei RPF1's (16lbs in 17x9) those are the two lightest and cheapest rims I know of that'll fit our cars. I'm going with the RPF1's in ESP myself. I think either set could be had for well under 1000 a set. Tires.....well I'm still not sure myself
RPF1's are more expensive than fn01rc's. But the RPF1's are also lighter. Are you prepping for a National level SP Evo? If not, than running a 245 Hoosier or V710 will be enough tire at the local regional level and probably even divisional level. I have 17x8.5 RPF1's with 245/40 Hoosiers and used the stock wheels with 255/40 Victoracers which was enough to win two different regions in ESP.
If you are at the national level you may need 275's and a rim at least 9" wide (probably wider) but you will also have serious rubbing issues on the front inside fender lining and will need to roll the rear fenders. Do a search and you'll find a bunch of info.
There are several members on the board that have used the 285 and 275 at Nationals.

I run a 17x9 rim with 275's mounted. The rubbing is not bad if you get the right offset (around +35mm).
basically you want to go with the lightest and widest rim you can afford.

Your best answer for the 285/30-18 Hoosiers is an 18x10. Your best bet there is CCW: www.ccwheel.com A set will be around $1800-2000. I wouldn't advise running a 285/30 smaller than a 9.5 or 10.
The cheaper option is a 275/40 on a 17x9.

Has anyone considered running a 17x9.5 with 275/40/17 in front, and a 17x8 with a 245/50/17 in the rear. The diameters are the same, and will allow the use of a stiffer front anti roll bar, and the clearance issues in the rear would be non existant. It only makes sense with a weight disrtribution of 60/40.

Mark,
I think someone tried that last year at one of the national or pro-solo events. Not sure how it turned out.
IMHO, it would be easier to overcome the weight distribution by properly balencing the suspension to your driving style

The viscous center limited slip was locking and unlocking constantly to keep the rear from spinning and that unsettled the car. Maybe it would work with the active center diff..... I'm planning to try something else for SM....

I am amazed that you didn't cook the viscous coupling.

I am a big believer in the wider front tire setup (as my co-driver would attest...) and spent two days in Peru, IN testing the wider front tire back to back with an equal width setup. I changed the suspension settings (spring rates, swaybars, alignment, tire pressures, etc.) to try to make the wider front setup happy and finally concluded that the difference in grip was making the center viscous coupling unhappy.

Eric, What brand of tire, and what was the differnce in tire diameter. With Hoosiers, a 275/35/18, and a 245/40/18, are within a tenth of an inch in diameter. The diff should not even notice that I would think. By coincidence it is the rear tire that would have a slightly bigger diameter. It seems as though the 17's are not available in the autocross compound to do this with 17's. What do you think.
Thanks,
Mark
