Anyone get coilovers with custom spring rates? Our car is a little weird most aftermarket are listed 8F and 9R, while most cars have a higher front than rear spring rate. (Like a 10k/8k or 12k/10k). I was wondering what your spring rates are, how do you like the ride, and how big a drop are you trying to achieve? Thanks! Hope to hear from you guys

 

I think BCR's come standard as 10k/8k. thats what i had and it rode great

 

How stiff or how soft did you set them? I feel like the GS is a really large car and was thinking of going 12k and 10k

12F 8R - don't think you can give credence to whatever the numbers are, it's going to vary for a variety of reasons, and not all to do with technical merit.
Unfortunately, unless you can drive a lot of GSs each with a different brand fitted, and set up to a standard drop, then you're just going to have to suck it and see.

If you want to play it safe, then stick with F-Sport springs and shocks - at least you know what you're getting has been thoroughly tested and evaluated before Lexus committed to commissioning them for production.
Even with Tein/etc, you have no real idea as to how much time was spent in testing.
