The popular 'G' chassis 2/3/4 series strut braces have been modified to now support both the G29 Z4 as well as the A9x GR Supra! The Dinan A9x/G29 Strut Tower Braces provide additional rigidity and sharper handling to the chassis by reducing flex under hard cornering conditions. With more control, spirited driving becomes easier and infinitely more enjoyable. Not only do the braces inspire confidence but they replace arguably the biggest eyesore in the factory Z4 engine compartment. Transforming the blight that is the factory smashed aluminum tubes into a notable highlight that augments the engine bay rather than detracting from it.
