Over the last 12 plus months, SIMSpec Engineering have been developing their own tyre sauce with the help of a chemist and many laps of testing at many tracks and classes.

Grip Hack tyre sauce improves grip for the entire run, not just for the first couple of hot laps. After all, it's consistency that wins races and this was the main goal. It works super consistently on smooth, rough and painted tracks. 

Grip Hack increases chemical grip of the tyre by putting oils back into the tyre. It works on rubber and foam tyres and comes loaded in a 75ml dauber top bottle.

Best of all it has less nasties than other goop and it's designed and made by SIMSpec Engineering in Australia!

Recommended prep:

• Clean with your preferred tyre cleaner.
• Coat tyres liberally and heat in warmers for 10-20 minutes.
• Wipe off excess just before your race or put the car down with wet tyres.
