Bimmerworld coilover systems

[Karlspackler]

Bimmerworld has VERY deep roots in racing and I was looking at their system for a light street/heavy auto-x build car.

I would probably couple them with Koni SA's(yellows)

Here is the link:

They are the 6th item down called "Coilover Converison Spring Kits"

They allow for full height adjustability and you can choose your own spring rates.

So the real question is, does anyone have experience with these? Quality? Etc......

[Karlspackler]

?? no one?

[asubimmer]

? umm...those are just GC's man

? umm...those are just GC's man

So are they good? Bad?

I am a e36 guy so I dont know e30's or their parts and I am planning a build. I plan/ask ass loads of questions before I spend money. It is how I work :drink:

[asubimmer]

pretty much anyone here that has coilovers uses GC'c, yes they are good ;)

I was satisfied with the quality of the coil overs I got from ground control. Everything seemed well produced ect. If you order from them be sure to remembre to ask for the "D rings", and the Koni gland nuts. Also be aware that a lot of the RSMs need to be modified to work with the Konis. Ground Control ones do not as well as a few others.

Thanks alot guys

why does your GC have progressive rate springs in the back??

my kit has linear springs all around...

[wazzu70]

I dont think they are progressive, I think the smaller coils are just to rest on the adjuster. The others are all the same. I think the pic also make them look a lot more dis-proportioned than they really are. Ill compare with a friends kit and see if there is any difference.

Those rear springs are weird. What is the rate/length?

Variance in the coiling diameter doesn't necessarily mean that the spring is progressive. Variance is coil spacing, however, is usually a sure sign that they are prog.

hey just copped the GC setup......And i need that pic......THanks

[robweenerpi]

That rear spring is an E30 specific unit. It's a 5.5 inch 475 pound linear rate. The coils are like that so you can run a low rate with out coilbind. It works really well with a 350 front spring.

You could also try the Tein kit bimmerworld offers. I was talking to James from Bimmerworld last weekend at VIR and he said they were having trouble dealing with GC now and that he would reccomend the Tein kit over GC.
