my car is an 05 comp pkg. Went with the P6 Bilsteins (Which are a 10mm BTW for anyone that needs to know). Bought a set of the Lemforder mounts to be cheap (I get them for under $10 a piece), but reconsidered that since I am a dealer for AKG and their part is superior to the lemforder stock replacements. I decided to go with their Poly RSMs. As far as the reinforcements, I have a set of akg here, but bought a set of the ecs just to see if there is any difference in thickness/quality. AKG plate is raw, ECS is coated. Figured I would decide which one seems better and throw it on my car. Thank you very much for the help!!

AKG poly bushings are not superior to OE BMW bushings

Talking about bushings. Any reinforcement plate would suffice, no need for anything fancy. You don't even *need* them, just some cheap insurance. Z3 plates are oe and more than adequate.

gotcha. Thanks. But doesnt the actual bushing in the mount provide lateral deflection of the shaft of the shock? Im not sure why you think a stiffer bushing wouldnt be superior in that instance, but im not a suspension engineer either, so you might be 100% right.

When I first got my ECS Monoballs there was a clunk from my rear right... I eventually narrowed it down to the monoball... took it off and it made a small clicking noise... which then when on the drum skin of a shock tower made a clunk when driving... I returned it and got a replacement from ECS... no issues since... quiet as a mouse back there... except for a diff / M-clunk I am now looking for which is unrelated to the suspension...

The tiny bit of isolation those monoball mounts have would be delrin or poly, so they're effectively solid. No way there's no NVH. Every part of the car suffers when you ditch the stock rubber, some more than others. Motor and tranny are the worst, subframe probably the best place to go solid. But the monoballs will offer precision and will allow full articulation, both moreso than rubber, so a good race car part. I just laugh when someone asks a question (in the general section, not track section) and people respond with hardcore parts, that cost as much as their entire suspension sometimes! I'm as guilty as anyone in buying into hype or thinking I need to mod; there's room for improvement. It's taken me years of modding to learn to stop and really think, "what does better actially mean?" I learned long ago not to read the vendor's advertising, but it was still easy to convince myself that every mod is good (and fun!). I wish more people would buy a 100k m3 and put all new rubber everywhere, get a good alignment and report back. Instead, we get people validating their chinese coilovers or race car parts for a street car that, maybe, maybe, sees a track once or twice a year if at all. "Not much more nvh" mmm hmmm. You seldom ever get something for nothing. Everything is a compromise/trade.

well, pretty much all of my current m3s are solid/poly mounts on everything and i have no complaints with NVH, but I definitely understand where youre coming from. Only "upgrading" the parts on my car because the rear shocks are original and the stock passenger side RSM has failed. Again, thanks for the knowledge! ![]() |
