I noticed on the 8E that it comes with Silver springs on front and green in the rear (standard on roller/kit) and have the top shock mounted in middle and on inside on the bottom. Not sure on what piston/oil though. I had a guy tell me that he uses 55 pistons all round (the kit does but the roller has 54 in front) and runs 40wt oil all round (40wt front on roller/35wt front kit - 25wt rear roller/35wt wt rear kit). Might try that setup a go. Have to wait for my ride height gauge to arrive to be able to measure the ride height
