Yes. Its more a question of will the wheel's offset allow you to fit the tire on the car.

just curious, but what tire do you plan on running?

kuhmo victoracer700, the escta v710 just came out, but i have not heard anybody using it yet, so probably go victoracer, getting the kosei k1 or slipstream in 7", but i need something like 30-35 offset (or even smaller offset), anyone have any suggestion?

thanks

i mean, what is an ideal offset for a 7th gen for autox?

I'm not sure on the offset...


Have you ever ran on an R compound tire??? You are so going to love it.......

I was running 20lbs rim 215/45/17 yokohama es100, h&r sport spring with blown driver side shock last year. Hope to have at least an average of 4-5 second improvement next season cuz i installed the kw v2 + gonna get lightweight 15" (around 12-13lbs) on victoracer v700

38-40

will 35 offset be ok?its gonna get a bit better grip, but trade off sharpness.

It'll be ok, under hard cornering, its likely to rub the fenders though. 225/50 is a lot of tire to be stuffing in there, and the rim itself will be out underneath the fender lips... I hope your car isn't substantially lowered or you'll be making a trip to the body shop after your first event.

i still have 2 finger gap all around , and will be on the most stiff setting when i go autox, but i might lower it to about 1-1.5 finger all around, u think its ok?

 
Rep Power: 423

doubtful... 2 fingers is about 1 1/4". The average suspension needs at least 2" of travel in each direction.
but do whatever you want if you think its going to fit, then do it. I highly doubt it will fit.
You're looking to take a tire thats only 1/2 an inch shorter than stock but 50mm wider (thats 2") and push the entire wheel/tire assembly out 10mm (thats about 1/2 an inch. So go to where your stock tire is, measure out another 1.5". If you think your suspension can travel 2" and your tire will clear the fender lip then it will work.
I have 37 offset wheels and 215 width tires and I'm sitting level with the outer fender edges. You're looking to push out another 12mm from there. Its very unlikely that in the 1 1/4" gap you'll be able to pull all that tire (when you factor in the fender lip you need to clear, you've got the wheel gap (1.25" to pull about 1" of tire up and in the wheel well). the suspension geometry just isn't going to allow it. Its a physical impossiblility. You could set massive camber angles, but what advantage does that give you?
There comes a point where its just too much and it won't work.

Just take a look at these pics...


Thats mid-corner then the corner exit. Thats about as bad as the roll can get....
now look at what it should look like sitting straight...


Cornering pretty much did away with the wheel gap from STOCK height. Stiffer springs will do away with some of that roll, but you're starting from a lower height.

umm...i'll see when the season start, last year i have 215/45/17 offset 45 with h&r sport (and broken driver side shock), i have no problem at all except rubbing of inside tire, that was about the same height I have after i got the kw v2. gonna try out when season start

thanks

and the body roll has improved alot now since i got kw v2, before i have rsx 19mm rear sway , h&r sport and front upper strut, gonna get cusco rear tie bar before season start

Well it sounds like you're gonna do what ever the hell you want to do anyways... so why keep asking for if someone else's opinion of whether its going to fit?
An extra 10mm of offset is a hell of a lot, its enough to change the fittment from one car to another, not to mention the extra stress from the increased moment arm on the studs, bearings and axles (then add in the increased grip from an R compound). The car will react totally different.
If you think it'll fit then have fun, but I strongly suggest you work out the math before you try it, its a pretty expensive oversight to have to repair quarterpanels and whatever else you'll bust if they collide. But if you're just going to go with what you think anyways and not even consider what was said at all, then quit wasting the time of those who answer by asking for even more info.

i didnt say i was gonna go 35offset, after your opinion i might probably get 40offset, what i meant was try out the first 1-2 times when season start and ask for more opinion from those ppl there than decide which size im gonna get for rim and tires. Anyways, thanks for you help
