Important Notes

• If the gap on your GQ is very minimal it is likely your roof skin has separated internally from the support beams, if this is so we recommend removing the roof lining and re sticking the roof skin to the support beams.

If you may add a rear wing in the future, we recommend keeping the tabbed bar and mounting it with the tabs facing inward for now.
