I put my set on last night, Bad azz, I will be putting these to the test all week and then some. I dig the adjustability. fit and finnish is very nice. Install was a simple and easy. Just pick up my XP, and last weekend in Glamis, Had a blast. After seat belts and seats for the first ride, I new shock were next in line. You can see right out of the box these are going to be a big improvement. Size, Spring length, and adjustability. I have talked to a few Racers that use them and they cant say anything bad about them. I have to give Justin at Cognito Motorsports big props for walking me threw these bad boys, he is the man. He has these in stock and will take care of you. Great Customer service !
