Do your thrust sheets work with this kit?
Does this kit fit the M3 rear lower control arms or is it designed to work with oe?Can you post the additional cost of switching to Swift springs on your website?

Spring rates are also in the OP, converted it's 336 front and 400 rear.
Swift spring upgrade will run you $570(with HPA rear height adjusters) and I will toss in the $50 worth of thrust sheets.
I think this is a typo..
Here is Swift's springs spec sheet.

Is this now the default spring rates you offer w you coilover setups?..b/c I did recall you use to recommend 392/784..last year
