The Cabrio Suspension Thread

[CorvallisBMW]

At least on my car, the carbio sports road high & stiff, exactly the opposite of what I wanted. Low & smooth is the way to go in a convertible.

HR Races are pretty stiff from what ive gathered. But def lower. What are you riding on now?

try to ignore the angle but focus in on the wheel distance. Both of my cars have coupe H&R sports, with all pads in, and 15mm drophats. There is a difference between models.

I am running. . .

GC coils with 460/650R
GC Camber Plates
Shortened Koni SA Shocks
CG Rear Shock Mounts
No rear bar/m3 style adjustable links on the front.
Coming soon modified front struts and rear subframe So I can crank them on down. (they are all the way up in these pics.:D)

UPDATE: Contacted eibach and ordered some tender springs and spacers to be able to run a dual rate setup up front as well as shortening the housings finally. Hopefully this will make the car behave a little better over expansion joints and such at speed without severely compromising handling in the turns, or having to raise the car drastically.

Correct me if im wrong but the coupe HR sports lower the rear more than Vert HR sports, right? And the front springs are basically the same?

On your pic, the front of the vert looks lower than the coupe. Engine weight?

Both have M20 (as of right now ;-)) but you are right, the cabrios front is lower (~.5" on wheel arch). Im not sure why but maybe it is the additional structure weight the cabrio contains.

I've got a pair of Eibach vert specific rear springs if any of you topless people are interested.

They are high, but not stiff. They have the same spring rate as h&r sports for a coupe/sedan.

I thought you were going with GC coilovers? Linear springs are not going to provide for a smooth/soft ride.

This is incorrect. The front h&r convertible springs will not lower the car as much as h&r coupe h&r sport springs.

He stated "basically" and thats what I was going on. If its drastically different, I stand corrected. If you have spring rates to compare the two, id like to see them as it would be beneficial to this thread as well.

Spring rates are the same according to the folks at H&R. Difference is the height, for both front and rear. H&R convertible springs are the same as H&R iX springs.

H&R convertible-specific sport springs = teh suck.

end of story.

My question is whether the HR Race springs will be stiff enough on a 'vert to run an aggressive wheel/tire combo............I have a feeling the answer is no.

Yes, they will. Promise :)

[TimR]

Can't read this whole post so yes or no, E30 M3 springs on a Vert.

Wishno87 is running that setup currently on his car and seems to like it as far as ride quality goes. It's lower than stock but not nearly as low as aftermarket springs. Maybe he can chime in.
