Does anyone know if the Powerflex rear shock mount will increase travel like the Dinan one does (>= 10mm)? The Dinan one is overpriced at $102, whereas the Powerflex is $64. Per my search I was unable to find an answer to this.

Thanks

No, unless you slice the bottom mount in half dinan vs powerflex

Interesting, I guess they are worth it then if they are the only ones that add the travel.

If you ask me, the answer is absolutely not. Just get the Monroe kit.

But the only reason for me to upgrade is to add travel because I know for a fact my car is hitting those bump stops almost immediately on larger bumps and that's giving me a harsh ride. Why the Monroe kit?

because is CHEAP, is made out of hard rubber, comes with HD thick washer, so if you slice the lower mount you will increase the travel and because the parts are sturdy it will be OK. Also, remember to shave the metal sleeve the same amount. Easy mod.

I would trim the bump stop off first, or get some shorter ones say from a ZSP car, before trimming the shock mount. OP did not say if he has lowering springs or not, but if he does and reused stock bump stops, that maybe why he's bottoming out in back. Plus that gives as much as an inch more travel vs a few mm. If he is stock springs and bottoming, something else is wrong back there.

It's all stock suspension. I'll look into the ZSP or Z4 bump stops

That's a very good reason....

Is this a 128? You should not be bottoming on a stock suspension, unless the rear shocks are bad or something else is messed up. Maybe you have wheels/offsets that are not stock or something. If that is the case shorter bump stops might not help as the tires are contacting a fender well or something before you use up travel. If you have stock wheels/tires too you can certainly try the shorter bump stops but that would be a band aid. Basically stock rear on these cars has a lot of travel, at least compared to front.

Yes, it basically rests on the bump stop at static height. It isn't bottoming out in the sense that the tire/wheel are hitting anything but it's the damper that's running out of compression stroke (hitting the bump stop) and that's causing the harshness. I'm going to go the ZSP/Z4 shock mount route as that is cheaper and sounds like it'll do the same thing as a thinner shock mount.

Oh yeah, no that is not good. What you can do if you want is trim off about an inch of that stock bump stop, without even taking the shock apart. Use a sharp knife or exacto, careful not to scratch the shock rod. See how it works, then go for some new shorter stops. Def should not be riding around on the stops.

Thanks, Will try it

When running lowering springs, the bump stops you want are E36 M3 in front (31332225377) and Z4M (33507836826) in rear. I have these plus Monroe upper (907984) & lower (907985) shock mounts waiting to go on the car as soon as my back-ordered UUC sway bars arrive. Probably not going to mess with any trimming of the Monroe mounts and just rely on the shorter bump stops to maintain my travel.

So if you saw 10mm off the bottom of the shock mount to increase shock travel by 10mm, how does that not lower your ride height by 10mm? Is that 10mm extra really making your ride quality a lot better?

Because the spring is what sets the ride height not the shock
