Yes, delrin is harder, so it will transmit more vibration into the car, however it is less likely to squeak like poly does. I have AKG poly CABs and they are noisy.

Yeah, my CABs still squeak, but its the vibration transfer that bothers me more than a bit of noise. My car is noisy no matter what though. The front control arm bushings are one thing that I don't think you can really go to stiff with as it really does make a difference and the harshness transfer isn't too bad. For most I don't think that the solid rear diff bushing or subframe bushings are worth it over urethane, and the rear trailing arm bushings are supposed to move on more than one axis. If you have solid (delrin) bushings there, they're going to be limited in terms of their intended operation.

All of this is my opinion/theory of course, and as with any discussion about comfort/ride it's all about what you find acceptable.

Hey all - just checking in.

Following careful consideration of all the discussion here and elsewhere, I have happily ordered the following bits: H&R Race springs, Bilstein Sports, Turner rear strut brace (I already have one at the front), Polyurethane bushings (rear trailing arm, rear subframe), and the Aluminium/rubber rear shock mounts from Turner.

Though I said I was mostly stock, the car also recently got fixed-3-degree camber plates, M3 offset bushings at the front and the turner chassis reinforcement kit. Those last two were installed by Sir and Master Glarner themselves - I recommend them highly whether you are local or not. (Think about it, get excellent work done on your car, while you get to drool / kneel at the sight of an M1 and more!)

I don't contribute as much as some to Max, so I very sincerely appreciate all the input you've all provided here. If I haven't followed your particular advice this time, don't despair: I'll be back after some more track experience. I'm "all-in" to my E30 for life. You've all heard that before, but I've had mine for 7 years now. It's been treated to a brand new M20 amongst other major things. So many times I could have bought something newer and faster, but I haven't. (My wife has a 335i so I do appreciate the newer stuff, but it just makes me appreciate the E30 even MORE!) This is going to be a 50 year car for me.

The shipment just cleared customs so I will post pics of shiny bits as soon as I get them!

Cheers again!

Hope you have better luck with those H&Rs than I did. Gave my car the rake of a dually towtruck and made it understeer like a bitch.

Here's what H&R Sport springs and Bilstein sports shocks will give you under hard cornering...,

Anyone have a compass to measure that angle?



Hopefully your H&R Race springs are much more stiffer if you plan on tracking... Don't get me wrong, the sport springs are still fun to track with, just not the best...

Fair enough - but this is me before the upcoming upgrade - and you don't even need any instrument to see THAT angle lol...
