How low can it Go?

Made new subframe spacers for the Wedge

So you are replacing two of the rubber bushing with one steel one? Is the frame supposed to flex at all?

Sorry - not leading questions. I just haven't fooled around with the subframe before.

I also asked that question and the answer was,"that's what the motor mounts are for."
Original spacers are 12mm 1 piece deals and I think Brad increased it to 23 mm with another piece. According to "How to Improve a TR7 or 8" Williams says you can go to 30 mm but I wanted to be safe .

The stock set up has one rubber and one steel spacer. The rubber spacer doesn't really do much, as there is a steel sleeve that runs thru it. The steel sleeve extends down thru the subframe and into the lower bushings. When you tighten down the subframe bolts, the steel sleeve acts as the limit on how much to tighten it. The rubber is just there to help minimize road vibrations. The slick setup is to install urethane lower bushings, a solid 30mm spacer and longer bolts. When you tighten everything down solid, the subframe acts like a lower strut bar and stiffens up the front end a ton. Add some welds to the front cross member behind the bumper and install either an upper or lower tie bar to really take the flex out. The only problem with dropping the subframe, is that it messes up the steering geometry a little. Adding taller tires and lowering the ride height makes things even worse. You will notice a little tramming on bad roads. That is where the steering tend to follow the ruts in the road. One big plus for lowering the subframe is the increased room you have under the hood for your four barrel conversion and air cleaner.
