The Cabrio Suspension Thread

[z31maniac]

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.

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

end of story.

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.

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

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.

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.

correct me if im wrong but the coupe hr sports lower the rear more than vert hr sports, right? correct. And the front springs are basically the same? correct.

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.

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.

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

No way, races are much stiffer than the cabrio specific sports. Besides the latter rides very high and stiff, they suck. Had them on my car for all of 2 weeks before I ditched them.

I passed on the Races and will try out the vert springs. Hopefully once i remove rear pads and insert drop hats up front i could live with the stance. If not, then I may go with Races but living here in Jersey potholes suck. Skidplate coming soon!

[CorvallisBMW]

Aren't H+R Race's floppy at the back with all the extra weight of the Cabrio's butt?

I would think Cabrio-specific springs are the way to go...?

[ubernasty]

What are some good springs that will get a 'vert nice and low? As in, lower than H&R Sport's?

Vogtland maybe? Any pics?

vogtland coupe. 1 dead coil cut off front, all pads in rear. billy sports
