On the black carpet, I am running stock side and center springs on the rear, 650 cst oil, 2 hole piston. Battery is forward about 6-6.5mm from the rear posts, 1-1.5mm rear droop, 15k oil in dampener tubes. CRC .50mm front springs, 4mm spacers above the steering knuckle, 3 deg upper arm mounts, long upper arms. CRC blue tires front and rear, or CRC spec front tires, blue rears. CRC blackart lola body. Had to add about 36g of lead to reach 730g min weight, this is a super light car! Car handles awesome.

Handy tip I figured out. Get a second shock mounting bracket and double up with the stock one. Stock 2.5mm screws are still long enough, just need a longer screw for the front shock mount ball. Less flex in the shock mount, more consistent handling, and less chance of breaking it in a hard crash.

Another tip, for the front ride height spaces. Take some extra 0.5mm spacers and apply one or two layers of thick clear tape to the spacers. I use Gorilla brand clear repair tape. Each layer adds about 0.15mm thickness. Now you can get between the standard 0.5mm steps, which is a big deal on carpet. I have one set of spacers with a single layer of tape for 0.65mm and one set with a layer on both sides, for 0.8mm.
