Backspacing with Ground Control coilovers.

Recommended Posts

Hello, everyone! 

New 1975 280Z owner. First post, but I have been reading on this forum for years. 

Couldn't find the exact information I was looking for while searching.

I need to know how much clearance will I gain with Ground Control coilovers. I would like to run 16x9, 0 offset rims in the front and I am lacking about 20 mm of clearance.  All posts I have read say that coilovers give more clearance without the exact measurement. 


With stock suspension in the car I have 122 mm (4.8 inches) from the wheel mounting surface to the spring perch.  

Appreciate your input.

Just received a response from Ground Control Suspension. 


"Hello Michael, 

I apologize for not being able to reply sooner, my e-mail was down for a few days. Our system adds approximately 1" of tire clearance over the original springs and perches. 




Hope this will help someone.
