where to buy springs for rear (used with coilovers)

[Sh3rpak!ng]

I have installed a set of megan coilovers on my e30 (don't hate, I know they are not "quality") and I would like to replace the rear springs with a higher rate. The kit comes with 8k front and rear but I would like to put a 10k spring in the back. (I will probably replace both front and rear springs with better quality)

My question is: where can I buy those "barrel" shaped springs for the rear?

I am assuming they are not the same as a "coilover" spring as listed on most websites since the e30 does not have a true coilover in the rear.

Thanks

Ground Control or Ireland Engineering sell pairs of Eibach coilover springs. You can but any length and rate you want.

i was just looking @ summit racing too, they seem to have a decent amount of options.
