I want to put my wheels on this spring, 20x9 +38 and 20x10.5 +45. I want to lower it but wondering if I should go with coils or RSR down springs. Anyone with experience with both let me know! I want an aggressive stance just not too low! And where is a good vendor to buy suspension from for the best price/customer service??

If you want to keep your adaptive, which is a great feature springs are the way to go. Whats great about RSR is they offer multiple levels of drops from mild, medium to maximum so you can kind of tailor your car to what you want. Here's some information on their springs, hopefully it can help you to make an informed decision.


Most Mild Setup
HALF DOWN SPRINGS
Approximate Drop:
Front -20mm to -25mm (-0.8inch to -1.0inch)
Rear -10mm to -15mm (-0.4inch to -0.6inch)

Spring Rates:
Front 4.60kg/mm
Rear 8.67kg/mm

Moderate Setup
DOWN SUS SPRINGS
Approximate Drop:
Front -30mm to -35mm (-1.2inch to -1.4inch)
Rear -25mm to -30mm (-1.0inch to -1.2inch)

Spring Rates:
Front 5.48kg/mm
Rear 8.98kg/mm


Lowest Setup
SUPERDOWN SUS SPRINGS
Approximate Drop (AWD):
Front -35mm to -40mm (-1.4inch to -1.6inch)
Rear -35mm to -40mm (-1.4inch to -1.6inch)

Approximate Drop (RWD):
Front -45mm to -50mm (-1.8inch to -2.0inch)
Rear -40mm to -45mm (-1.6inch to -1.8inch)

Spring Rates:
Front 5.10kg/mm
Rear 8.16kg/mm

I hope this information helps you. Also if you have any technical questions, let me know I used to work for a suspension company for a number of years and used to be really into suspension and suspension setups.

Cheers!
