PHR questions
PHR questions I recently bought a '97 WS6 and I'm in the process of upgrading certain parts. It came with some brand new BMR springs and SFC, which I'm having installed now. I'm also getting ZR-1 replicas, 17x9.5 (+38) and 17x11(+50) with 315's in the rear. I understand that adding the 315's alone will probably make an adjustable PHR necessarry. Adding the drop will only increase the need, I'm sure. So, the question is, how much of a difference am I looking at without the PHR? Will it even be tolerable to drive until the PHR gets here? Will the wheels/tires fit at all without the PHR?

It's not an issue of tolerable or not. And more than that, I can't say if the wheels and tires will fit without it either. If the tire is rubbing you will damage the tires and/or wheels if you try to drive it without adjusting it. If you need a good PHR, talk to Trackbird on this board.
Thanks. I talked to another guy on this board who has a WS6, 1.5" drop, 315's, and stock PHR with no rubbing whatsoever. But you're right, they may not fit at all, so I ordered a PHR. I got a great deal off ebay.
Can you be more detailed? Are you getting tire rub or is the bumpstop rubbing on the inside of the rim?
If the tires are rubbing on one side more than the other, just lengthen or shorten the PHR to help balance it out. Once both sides are rubbing equally, you will need to hammer down the high spots. Black paint over the exposed metal and drive it for a few days. Then check for shiny metal spots.
If you do a search on this forum you will find a lot of info on fitting 315's.

Well, I'm not exactly sure where the rubbing is at on the body or bumpstop. But the only thing I can see on the wheel/tire is scratches on the inside lip of the right wheel. There's no evidence of the tire rubbing. It only does it around tight (left?) corners when I try to slide it. I can here it rubbing then. I'm assuming it's contacting the top of the bumpstop, since that's what sticks out the most, and it's closest to the wheel lip. Were the bumpstops removed in that photo^? I don't see them.

Yea, they are not in Manny's photo. I cut my bumpstops off completely, also just so the rim wouldn't get hung on them when jacking the car up and to make sure they never scratched the rim.
Jack up the rear of the car and find out what it's rubbing on then we can figure out a fix.

Verdad Gallardo I just moved and I don't have a floor jack here yet. Once I get that I'll figure it out. Are there any problems from removing the bumpstops? What did you use to remove them?
I used a cutoff wheel in a air drill. Removing the bumpstops is a whole big ordeal that will require you to do a lot of measuring of the shock and it's compression limits as well as the suspension travel etc... If not done properly it can damage your shocks, so I wouldn't recommend it.

I would not recommend it, instead you can trim the factory bumpstop a little on the sides. Like this:
