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..

6Kg- 336
12kg- 672

Here is Swift's springs spec sheet.

Swift Coil Over Springs _Parts & Spec Sheet.pdf

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
