By popular demand, we are now offering these steering arm bump stops for all Aston Martin Gaydon Era cars. These have been developed and tested across multiple race series and seasons, and are available in 20mm sizes.

For those that wish to run wider front rubber (GT4 cars run 18x10 front & 18x11 I believe) you can now fit trackday wheels and tires without risk of rubbing the bodywork.

Yes, $199 is a fair bit for a couple of pieces of nylon, but this is not something I would take any chances with. These are properly engineered and tested. A poorly made bump stop that fails will cost thousands of dollars in damage in mere seconds!
