How will 235/40/R17 fit on 17x9? Will they be ok performance wise. I am planning to put 255/40/R17s on but my current tyres still have plenty of meat left and don't want to just throw them away.

No issues at all. Very close to the stock size except for the lower 40 series profile. As you noted, the 255/40 will be a much better performing / looking tire (the 255/40 is the "gold std" in the 17" diameter)

Will I need to get the guards rolled with the 235/45s on? Wheel will be 17x9 +22 and car will be on factory suspension.

LOL, we didnt address the offset. Yes, running the +22, i feel, the rears must be rolled to avoid tire contact. The 235 helps the situation but the tire will likely contact the fender during a compression bump

Running the 255/40 on the +22 will need more than a roll. You will need the rears pulled & the bumper bolt relocated

How about the fronts?

The fronts are much more forgiving, but expect some liner rub at lock positions. As long as your ride height is not too low (fender to ground at approx 25 3/8" or higher)

sorry i meant to respond to this earlier - i can take whichever measurements you'd like.

i will do fender to ground, what is c/l of hub to underside of fender?

i think my rears may need a touch more camber, but i think i've got enough gap that i should be good. i'm nowhere near the bumper bolts on these 265/35s as well, plenty of room there. decent clearance to arms and ton of clearance to rear suspension. my front suspension is close to the springs but they shouldn't make contact.

Just measure under the fender to ground & compare to mine at (Front 25.375" & Rear 25.000"). My fronts have prob 3-4 fingers worth of gap but the rear is kinda squatty at zero finger gap / 25"

BTW, C/l = center line

will do!

joe,

these may not be 100% accurate, as i'm not on a totally level surface, yada yada, but close enough:

driver front: 26.75" fender arch to ground
driver rear: 26.5" fender arch to ground
pass front: 26.5" fender arch to ground
pass rear: 26.25" fender arch to ground

difference side to side likely due to corner balancing. so, i'm a considerable ways higher up than your car. i like having the clearance that i currently do, maybe the rears could be a touch lower relative to the front for better geometry

Thanks Sam

That tells us where youre at ride height wise. Yeah, side to side is most always a diff figure, corner balance or not

If you need the ride height, thats no prob. But if you wanted to go lower, you have some room there for sure

Even at my ride heights, I have no problem w/driveways & other road irregularities

yea i'm definitely riding higher than most evos - as of now though, pretty happy with the clearance and such.

the ride height difference may also explain the differing clearances between the tires and coilovers between left and right fronts.

alright guys, anyone have any info on this car as far as wheel specs go... my guess is they are likely 17x9.5 +28 or 17x9 +22. The tires are likely 265/40s. I am sure some of you have seen the video on Youtube.




I am currently torn with either going with 17s or 18x9.5 +22 which is very common and many folks have done this set on their Evo 8/9s as seen below. This car belongs to someone here on the forum. I am ordering Fortune 500s for my Evo this week so I will be adjusting ride height on it.





Below is my car... I am currently on Spec Rs with CE28Ns 18x9.5 +15. 255/35 Firestones.




I like the way the 17s look with the meaty tire as the 17s allow for more leeway for obvious reasons. So anyone with 17 TEs or has experience with them, tryin to identify the specs on the car above.

Need some help trying to decide which Autocross wheels and tires to go with. Suspension consist of Ohlins DVS.

want to stick with an 18X9.5 but lost on the offset. Keep finding +38,35 and even 22 work. going with RE-71 or R-S4 for starters at a 255/35R18? then plan to move up to 265/275.

if i have to roll the fenders not a big deal. just don't want to get wheels that won't work for my plans or if i have to go crazy to get them to fit as it won't be easy for me to get another set.

car is strictly autocross and gets trailered to and from. thanks

Its hard to nail down the exact wheel spec youll need, but generally speaking:
18x9.5 +34 to +38 may be OK running a 275 w/just a tight rear fender roll

Offsets lower that +34 will likely require a bit more rear fender work (i.e. pulling, bumper bolt re-location etc). And certainly, in your case, being that this car sees aggressive track driving, any form of rub can not be tolerated

If youre at a point where you have zeroed-in on a wheel, I can give you a better idea on what work is needed.

As an example, my set-up is fully cleared for the track: 17x9 +29 & a 17x9.5 +30 (275/40/17's). This set-up needed the full compliment of rear fender work (rear fender pull, roll, bumper bolt & a few other tricks to get this to fully clear)
