Rod Summers G35 track car at Road Atlanta putting the Z1 front control arms to the test.

 

In stock

 

Bump

 

 

The Z1 upper control arms are in stock available in race or street.

 

One of the most noticeable differences is the turn in response from the added caster the Z1 arms add.

 

Z1 control arms FTW!

 

Here is an updated picture of our Z1 arms.

 

ordered - helpful as hell on the phone, and recommended the lower urethane bushings to compliment the new UCA's. Installing tonight. I bought a second set of factory rays to make a square setup (all rears 245/35/19) and we'll see if I can get tires to last more than 3-5k now...

 

This is one sick G. What size rim and tire are you running.

 

How much do these arms increase caster, and what effect would this have on tire wear?

My driver's side is already near the limit of "spec" for a coupe on sport suspension, not to mention low speed steering is already heavy enough IMO so I would like to avoid a big increase in caster angle.
