Rear spring platform height adjustment

[Cubieman]

I bought a MCS 1WNR kit from Bimmerworld and they sold me the RE perches and 5" springs. They work.

Yeah, I have been looking at 5" springs as 5.5" are not so common.

I would like to stay with a progressive spring if possible. Maybe I'll reach out to TCK and see if they have anything.

Well I guess I am stuck with traditional adjusters, TCK offers a 5.5" 500lb beehive spring but say it will bind on this chassis.

Maybe someday if I go to stiffer springs I'll be able to use these RE adjusters.

My BC's had 5.5" rear springs, they were swifts, I don't know the rate unfortunately but I'm sure it was significantly higher than 500lb.

I just don't care for the design of the TCK perches, they didn't machine a flat base on the bottom. So there is very little surface area on the control arm.

I may buy RE'S traditional style perches or maybe just some ebay ones, simple part.

Eibach makes a 60mm non beehive 514lb/in spring in a 5.5 inch length. Eibach 140-60-0090. 2 inch block height so I wouldn't worry about spring bind or needing a beehive spring.
