2.5" Springs

[5Toes]

I searched, and I couldn't find anything. Maybe I suck? I dont know

Anyways are any modifications required for these, because I know like H&R sport, etc. are 2.25" springs. The spring perch is what would need modified right?

H&R Sport, etc are not 2.25" springs, but instead are the same diameter & configuration as the stock springs. 2.25" springs are used on coil over conversions.

The cheapest and easiest way to use 2.5" springs is to just buy the GC conversion kit. Really. By the time you purchase a set of springs and assemble perches, you'll spend more pretty much any other way (unless you have access to a machine shop). Also, they include an upper perch so that you can retain the stock strut bearing for cost savings.

Then what diameter are stock springs?

[nrubenstein]

I've never measured. They are more like 7". Haven't you ever looked at them?

Dont you dare become a stancewhore when you get your E30.

No I mean like diameter. aren't the stock springs 2.25" wide, not tall?

Becaue like straight racing springs are 2.5" wide, like H&R ID race - http://www.hrsprings.com/products/id-race/

OE front springs are about 5" in diameter. Rear springs are closer to 6" and are beehive type with the top and bottom coils being much smaller that the central part of the springs.

H&R Race and Sport springs match the OE springs as to diameter, though they are shorter and stiffer. The springs you reference in the previous post are for coil over configurations.

Dude, you need to pay more attention. Look under the damned car, or find one on the street if you don't own one. Or just look at some pictures.

(Also, here's a hint: a 6" long spring in the stock rates wouldn't really be able to hold up the car.)
