Front susp Q and rear wheel Q

[NJ Torque]

On a 17x11 ZR1, can a 315/35/17 fit under a 4th gen with no rubbing and no spacers?

Also, what are the best coilovers/struts for the front?

Thanks

At stock ride height, they will fit with no issues on most 4th gens. If lowered you'll need an adjustable panhard and most likely need the fender lips rolled too.

I think most people go with an adjustable panhard bar and that seems to recenter the rear so thatyou can put in the large 315's.

i have 17x11 ZR1s with 315s and i have no problem with two people in the car. but if i had one or two people in the back seats then the tires rub. but i dont have rear seats anymore so i don't need to worrry.

they do if you get them in the 4th gen offset, the 17x11's i put on my 3rd gen came off a 4th gen, he said he hammered the inner fender a little but probably didnt have too

You want to trim the bumpstops or they could damage your wheels. If you go with the Sumitomo 315's they tend to run narrower than the other brands and you can clear without rubbing if you have the right backspacing.

I didn't have to do any modifications to my car until I went as low 1.5" in the rear. I need to roll my fenders. I've been running 315's on my car 05' without any serious issues. The would touch the fenders once in a while if I had passengers, but other then that no issues.

Remember when no one else did? lol Sumitumo what? hah.

Im running ZR1s with 315 sumitumos outback and 275s up front. This is with the SLP Eibachs I got from Alex, and I get no rubbing. No mods done.

I guess one unholy thing is different, right Alex? lol.

If they run so much narrower, are they really 315s? :lol:




(yes, I know 315 is section width not tread width lol)
