Installed 315's this weekend

17X11 ZR1's with 315 BFG KD's, with Hotchkis springs and Hotchkis single adj PHR.

What i did:

- Had the fender lips rolled by a local shop
- Banged the inner fender wells (not much was needed)
- Cut the bump stops off completely

Results:

- I think i may need to have the fenders rolled up some MORE. I honestly have no clue how any of yall have been able to get away with not rolling the fenders at all. Mine are rolled a pretty good bit, and i saw "rub marks" on both of the outter side walls. It was much, but i did see it. I live in a apt complex with a parking garage (and the angles of the upramps from level to level are pretty steep, which puts unusual loads on one side or the other when turning from the steep angle to the flat level), so im not sure if that is it, or if its from the rear end squatting from a 1st gear punch or what.

- I thought this was going to be a bigger issue than it was, the passenger side needed about 2 square inches banged in from rubbing, i think i could have eliminated any inner well hammering if i messed with the PHR.

- I dont know if the bump stops needed to be removed altogether or if i could have gotten away with just a little trim. I didnt feel like measuring or guessing, so i just took them off completely.

All in all, it was a painless experience. The tire/rim combo looks great, and i dont think the slight rubbing issue will be much of an issue.

so did you not even adjust the PHB?

what springs do you have?

I didnt adjust the PHB at all.

Hotchkis springs.

adjusting the phb should fix your fender rubbing problem. I have one 315 that will probably always rub my rolled fender bc I had some body work done on my drivers side and it wont allow it to get rolled all the way. but overall. my adj phb when I adjusted it helped ALOT with fender and inner fender well rubbing.

How much does it generally cost to get the fenders rolled, enough to fit 315's ?

if you have someone do it. about 25 a side. I paid 25 for my passenger side. and then had a shop redo both for 75 a few months later. so overall. I paid too much. :(

I wouldn't have cut the bumpstop off completely . . . :eek2: There is no need to touch it at all!

I cut mine off completely as well. You need to if you want to set rims in as far as you can. well.. you don't need to if you want inner rim damage

No problems with them hitting bumpstops here???Just lift it by the rear end and don't take any sweet jumps.

I agree PICS OR BAN!!!

My dealer trimmed my bumpstops. The mounting holes are still in place, so if I ever want to put them back in, I could.

I have Yokohama AVS Sports, which are a very wide tire, and I did have some issues with the fender lip rubbing on the passenger side rear, however, that hasn't occurred again since I put my UMI double adjustable rod ended PHB in there.

Can you measure your BFG KD? I am curious if they are wider that the Yokos.

I have been running 315's on 17x11 ZR1s for over three years and never rolled the fenders...I did use the BFH :judge: on the inner wheel wells and did major trim work on the bump stops..the only place mine have ever rubbed was on the inside of the wheel wells I just use the BFH :judge: till it doesn't rub anymore .... :)

I have a few i took over the weekend, but it wont let me upload them because theyre too large.

Ill try and take some better ones tommorow, host em, and post em.

Running 315s with no BFH, stock bump stops, and no rolling of the fenders; also running Hotchkis springs, Koni shocks, and Spohn APHR.

Judging by the pic in your sig, you're running Nittos, which is the reason why you don't have to make any mods to your car since Nittos are notoriously skinny for their size. Throw some Yokos AVS Sport, Good Year GS-D3, or BFG KD on your wheels, and you'll break out that BFH in no time! :D

:werd: Yes that is correct..if he runs some phatt 315's instead of those skinny Nittos he'll be looking for the BFH :judge: for sure .. :D
