The question on how thick of spacer to get is determined by how much the car has been lowered from the stock ride height. You ideally want the LCA angle to be at what it was when at the stock height (a downward angle from horizontal), if the LCA is horizontal or at an upward angle then you will have to determine how much of thickness you will need to achieve the stock downward angle. 1" or 1.125" would work just fine for most applications where the car has been lowered but not slammed. Ok, I will put you down for a pair.dscottdatsun wrote:I would like a pair! Please! (Mama told me to always use my manners) How much difference does the height of the spacer make? IIRC the NISMO spacer was an inch, so I'll go with that. I am not looking to put my ride on the floor.
