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?
This is an oe setup, not a conversion kit as listed above.

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.
