I put H&R street coilovers on my car a few months ago and while I love the ride quality I found that the rear bottoms out very easily now and the wheels hit the upper metal bumper mounts inside the wheel well.
I set it up extremely low to start with so I raised the rear about 1/2 inch last weekend. It's better, but still bottoms when it really shouldn't. The H&R docs suggest reusing certain parts from the stock shocks/springs they are nebulous at best.
I saved the old bellows and what is called "additional springs" part number 8 on this diagram.
I suspect this part may prevent the coilovers from bottoming out. Does anyone have any idea if these need to be reused?
I don't want to R&R my coilovers to install these if they won't help.

 

How many miles were on the stock dampers that were fitted with the HR springs. They may have needed replacement at the same time

 

I didn't install lowering springs, I installed coilovers. I'm asking if others that have installed h&r coilovers or similar ones like pss9/10 if they had to reuse the parts I identified in my post to eliminate bottoming.

 

Sorry didn't read it carefully enough. My apologies I've not hit the inside with my ohlins but get a bit of rubbing w/ 315/30/18 and I am on the highest setting on the springs.

 

I installed H&R coilovers a couple of months ago.

I did re-use the bump stop (#8 in that diagram).

It could be that or it could be that you are just too low for the setup.

There should be no bottoming with the H&R Street coilovers when it's all setup.

 

This is what I was looking for. I really wish they could spend 5 minutes to include a sheet of paper indicating which pieces to reuse with the new coilovers!
At first I thought I was too low also, but after raising the rear 1/2 inch, it looks worse and still bottoms when I know it shouldn't. I'll have to pull them out and put the bump-stops on the shaft.

Thanks for the feedback, rep for you!

 

Hang on... I. Lied to you...

I just went and looked to be sure... I didn't use the OEM bump stop.. Just the stop and boot that was on the h&r strut.

Sorry for the confusion... I remembered a bump stop but got to thinking whether it was the OEM or not.

Here's a pic of my rear (on the lift) happen to be doing other work

 

Not sure if this helps you at all because it looks pretty much the same as the pic that mxracer posted above but I got this pic straight from H&R install sheet (disregard red arrow)....

 

Again, not sure if this helps but this is from an instruction sheet from H&R. It says: "The OE bump rubber has to be replaced by the supplied bump rubber with dust cover"....

 

This is the page that wasn't included in the box with my coilovers. The page showing ride height was there and a couple of brochures for their spacers and sway bars also came with them but not this important piece of information.
I Guess I won't put the OE bumpstop back in since mine look exactly like the photos posted. I have to figure out how to keep it from rubbing without raising it anymore. I had H&R lowering springs on it before and the height was the same as it is now, but it seems to rub more easily now.

 

typically the lower the car, the smaller the bump stop, because the strut now has less travel. I have had luck in the past simply cutting down the OE bump stop if the kit did not supply their own. This is obviously done at your own risk but it does work well. Basically it gives the strut room to fully travel and perform its valving... right now your strut is interrupted by the bump stop before it can accomplish this.
