Intro

This post is about Wisefab Corvette C5 and C6 angle kits. We have combined Street and Pro kit installation guidelines into one post. First we will take a look how to install the Corvette Street kit. Which is essentally a Pro kit with out Wisefab Control arms. You can always update your Street setup with our Control arm kit. Be sure to check out the Corvette halfshaft kit as well. Rated at 1500hp.

Street kit

Welcome Corvette C5 and C6 Wisefab angle street kit for OEM Arms. The Street kit. Here is a view of assembled components in the right corner. OEM Tie rod will not fit. You will need Corvette C4 Tie rod with the part number 21011026 for this angle kit. We have included hardware for the OEM arms. Lower control arm bushings and upper control arm cone shaft with hardware. These parts will connects Wisefab Corvette knuckle with OEM control arms.

Installing the Lower Arm Mounting

Remove OEM ball joint and install the Wisefab Lower arm bushing using a hydraulic press. Press this bushing from the bottom of the knuckle. Install the C-clip rings from the top.

Installing the Knuckle

Wisefab knuckle has two setups for lower control arm mounting. For the Street setup OEM LCA use the inner mounting point. Use the cone bolt and hardware to install the upper control arm with the knuckle. Check for clearance. There is a section on the lower control arm that you need to grind. Check the picture. Wisefab lock kits include adjustable hexagonal lock stoppers. Where each side has a different offset. The more dimples, the more offset and by that less usable lock.

Installing the Tie rod

The rod end with spacers has different height spacers. For the Street setup upper spacer must be 13 mm high and lower spacer 9 mm.

Installing the Lower Arms

Our lower control arm installation is quite straight forward. Insert the arm into factory lower control arm mounting slots. Tighten with bolts. We recommend using new bolts and nuts. Wisefab has built in a double adjuster on the lower control. For a convenient on race track camber and caster tuning. Lower arm has a built in camber/caster tuning with Double Adjusters. When you want to adjust camber you will need to tune both adjusters the same way. Caster is set by tuning adjusters the opposite way. Wisefab has included Anti rollbar mounting with the lower control arm. OEM anti-roll bar may need some modifications to fit. You should uninstall anti-lock bar when you want extreme steering angles.

Installing the Upper Arm

Our upper control arms are not symmetrical for the Corvette chassis. Make sure that shorter link is facing forward when installing it. Check out the picture how the body mountings position must be. Shorter end must be inside of the upper control arm. Tighten rod end locknuts after installing the upper control arm. Wisefab has included some spacers with the upper control arm. Those will come handy on the next step.

Installing the Knuckle

Use a M12 bolt and nut when installing those upper control arm spacers. Press those spacers into knuckle upper spherical bearing. Tightening the M12 bolt. Make sure that all the surfaces are parallel while tightening. Install the knuckle to the upper control arm. There are two setups for the lower control arm. Where the inside mounting point is for the OEM Corvette C5, C6 lower control arm. The second mounting point is for Wisefab lower control arm. Same applies with the adjustable lock stopper. Wisefab lock kits includes hexagonal lock stoppers. Where each side has a different offset. The more dimples, the more offset and by that less usable lock. Connect hub with OEM bolts, but use 3x M12 washers which came with knuckles. Add rotors and calipers.

Installing the Tie rod

Wisefab Corvette kit tie rods have non symmetrical spacers where one is 9mm high and the other one is 13mm high. Upper spacer must be 9 mm high and lower spacer 13 mm.This affects the bump steer of the car. For a parallel steering setup on a Corvette C5 you can use the Zero Ackermann washer. But on the C6 chassis you’ll need to use the 3mm Ackermann washer for parallel steering setup. Offset towards the the wheel. If you are using the Wisefab Rack offset kit setup on the C6 then use Zero Ackermann washer.

IMPORTANT!

Be sure to check the clearance in all extent of the suspension travel when istalling Wisefab suspension kits. Remove the coil springs for that. If there is clearance issues then change your wheel alignment or limit the suspension travel.
