There is a thread on hear discussing the springs...Swift springs.

As for camber kit, unless you're going full lowering, you don't need a camber kit. Anything within 2" or so should be fine as is.

I would highly recommend a camber kit especially if you're going to lower your car with coilovers. I bought a rear set of SPC rear arms (part # 72240). The best deal was from B2Autodesigns.

It's really only needed after you drastically change the geometry of the car...if he's only lowering slightly (less than 1.5" or 2")...he should be okay. I had no issues with alignment or tire wear on my 07 and I was lowered ~ 2in. The guys who do my alignment were able to work on it just fine. Anything more than that and you will likely definitely need a camber kit.

Camber is one thing, it could throw his toe off though. I lowered my G35x with Eibach spring and I had to replace the toe bolts to get back within spec. If you're already get the suspension installed, might as well throw in the correction arms in the rear too. I learned my lesson with my old car, better safe than sorry.

In the rear, did you install only the camber arms? Or did you need to add adjustable toe arms as well to get it into spec?

With regards to spring rate; see replies I've been getting from SCALE about our cars.

Q: About spring rates; the rates you listed seem a bit high and also quite a difference between front and rear. BC Racing lists 12kF/8kR a difference of 4K as opposed to 6K difference F/R for Scale. Could you please clarify the spring rates for the M37X?

A: For the spring rate, 12kg front springs will be close to oem stiffness so if you want like oem comfort level we will suggest you front 12 /rear 06 kg rate but will not be good to lower your car more than 0.5 to 1 inch from stock to avoid contact with the ground on hard corner or huge bump.

A 14/08kg rate will be perfectly balanced and will result on a 15-20% stiffer feeling that oem and will be good to lower from 1 inch to a tire to fender fitment.

If you want to go even lower, we offer the low version that allow to lower the car to hide half of the tire and use a harder spring rate ( 16/10kg ) will be surely a bit more bouncy but this it what you need at this ride height to avoid tire to fender contact or scratching on every bump you hit.

Q: Can you speak to the F/R difference? 6K difference for Scale vs 4K difference for BC? Is it the AWD?

A: Yes for sure, First our products are designed and tested not only for stance but mostly for handling performance improvement. We always check what the other brand use in term of spring rate, and what we found is with double wishbone like your application, they mostly use softer spring and customer state that the front is too soft compared to the rear. On any double wishbone application we have, the only application using a 10-12 rate is the Honda civic EF/EG and you know the weight of those cars are way less than yours so a 12kg spring is soft like oem and will not result in a performance upgrade.
For the rear, the 8kg spring is the best setup for the suspension configuration when using a true rear coilover system on this application.

Like i told you earlier, When we design a suspension, we try to match the front and rear to gain 15-20% stiffer than oem , On your application , a 14/08kg rate will give you exactly 18% stiffer on the front and 15% stiffer for the rear, this is close to the perfect balance, a 12/08kg will give you about 5% stiffer than oem for the front and 15% on the rear. This can result in a weird feeling over bump.

Of course the awd application is heavier that the rwd model and will need a bit stiffer spring rate
