Most durable brand of poly bushings and engine mounts?

[E-rich]

what he said.

anything poly or delrin really. i just did IE poly subframe bushing and delrin IE trailing arm bushings and an akg delrin diff mount bushing. huge improvement. also, look into a 4 point cage at minimum..dont forget bout your control arm bushings as well. i just did m3 offset as recommended by ireland engineering owner.

sweet, i just ordered off-set delrin bushings and new control arms, plus i have my solid aluminium subframe mounts, and delrin diff mount. i glad to see i made a good choice.

Let me know how you like these, i have been thinking about getting them.

Also, are they worth the price and the pain of the install? And are they that hard to install, many people dont get then because they say they are too hard/PITA to install.

Just remember these would put you into a very high autox class. After some double checking they are not legal in ST, OR SM. By grinding the slots into the mounting point you are changine the mounting point.

Just something to think about.

Considering the rear suspension GAINS NEGATIVE camber on compression, and toe in, I would think we need to minimize negative camber somewhat. Maybe -1 degree in the rear, even if at -3 or -3.5 up front......I'll try and find the camber curves that Gustave posted on the E30 trailing arm suspension.

Looks like thats what I am doing soon :)

In the looking around I've done I can't find aluminum subframe bushings.......Vac sells an aluminum diff mount but I'm still looking for subframe bushings.


Where did you pick these up?

You dont want aluminum subframe bushings unless its a track car.

[DSP74]

I know.

[nando]

I know.

lol. captain obvious much? :p

after looking at gustave's trailing arm curves again, I'm not sure I even want to bother with the weld in TA adjusters. I don't really plan on going any lower in the rear, and less camber would just make me rub the fenders more - I think I might sell them and go with 75d AKG bushings instead. I have urethane now, but the crap IE used to sell doesn't really fit right and the TAs actually move side to side a bit..

Turner has them and AKG has them.

Just curious why you decided against them given the info from those camber/toe curves?

[einstein57]

i went with the bav auto kmac style. The squeak like hell at speeds under 10mph but do the job. And no grinding required. Just a lot of patience. lol

because I can't change my camber (for tire clearance reasons) and I'm not convinced there's anything wrong with my toe settings - I'll have to get it on an alignment rack before I decide for certain though. at this point I'd rather have new springs and bushings.

[DSP74]

OK got ya. You can't run LESS negative camber as the tires would rub......That's what massive fender rolling/flares are for ya know?

[nando]

I actually pounded mine out with a sledge - it rubs on the upper/inner part of the fender, not the lips. :(
