Installing Coil Over Shockers in HQ-WB Holden
To install vertically mounted QA1 over shocks requires removing the original upper crossmember from the chassis rails, creating clearance of the floor panel to install the units and reinforcing the chassis rails before installing the crossmember and bracketry. Adjustable upper and lower trailing arms were also installed for maximum adjustability.

1969 Camaro Suspension Mods
This Camaro was bead blasted and found to be not in very good condition. We had to fabricate new rear chassis rails and set them in to be able to fit the 20 x 10 rims and set the vehicle up to sit very low. As we were designing a bolt in tri 4 link QA1 coil over kit for this range of Camaros we incorporated it into this vehicle. The diff is a new heavy duty housing and 35 spline floater, the brakes will be 330 mm units.
