Default Suspension Question

96 corvette lt4, front suspension question:

I'm about 2 days into installation of the midamericamotorworks wedge lowering kit and getting a little frustrated. I have removed the original rubber located on the top side of the spring and installed the wedges.

When I reinstalled the leaf spring, even after cutting/modifying the aluminum retainer, the wedges do not sit flush with the frame (top of wedge on the top of the spring to the surface above the leaf spring), and the bolt does not have enough threaded surface to press the wedges flush to the frame. Is this normal?

On the stock suspension, is the leaf spring engaged with the surface above it at all times, or does it have some travel before the original rubber would contact the surface above it.

Any help would be greatly appreciated, as the car is just sitting on jack stands at the moment.

Is it possible you did not take enough off of the aluminum brackets? You should had to trim them some with a SawZaw for them to go in flush with no play. Make sure the wedge did not move either because that will throw you off too. I did the same mod on mine and I had to make sure I trimmed the right amount off of the brackets for them to sit flush. As an alternatives too you could try and take more off of the wedges and then re-trim the brackets.

I did trim the aluminum plates down to about 1/16 below the top of the wedges. After calling and speaking with a number of tech's and engineers, the wedge will not contact the frame when the springs are not loaded. Only when they are loaded such that the shock can be mounted will they begin to start touching the frame. This is why everyone on the forums say the wedges don't have to rest on the frame, while all the installers say the wedges do have to rest on the frame; two different points of reference. Everything was reassembled with the aforementioned set up, and the car rides like a champ.

I'll post some picts after I get it back from the alignment shop.

Thank you for your response.

Doing the same to my 89. My directions say to install the wedges into the pockets on the frame and not the spring itself. How much did you cut off your brackets. A reference would be great. Did it make the ride any harsher. Send pics
