Am interested if anyone has tubes in 3rd gen car am redoing car and cant find any info on installing tubs is it possible and if so worth the job ??

 

Good question....I would like to know where the springs, shocks, and frame rails were relocated.

 

I am in the process of installing mini tubs. Unless you want to get into major reworking of the body the clearance gain is 1 1/2" inches on each side. If you are looking for a larger gain back half the car as it will be a better car. But, back halfing will also require a cage. If you will be happy with 1 1/2" per side it is still a lot of work but the rear "frame" sheet metal and floor pan remain basically stock. I made spring buckets with height adjusters so I can set the ride height with any rear springs. The gas tank must be removed and when the work is completed it will just fit between the new buckets. It will also require some metal trimming to get filler neck back into place if you choose not to remove it from the tank. Then I cut out the factory spring mounts using the new mounts as a template centered 1 1/2" inboard of the stock mounts. I used 6" ID shedule 40 pipe for the new buckets. Fitting them through the floor was a time consuming process as the floor pan is two layers of sheet metal separated by about a 2" space and the holes must match and be tight enough to weld the upper floor to the bucket. The side of the factory spring mount protrudes into the wheelwell. I removed a small section of it and hammered the rest of it flat and welded it to the side of the new bucket for additional "frame" strength and bucket support. The new bucket comes close to the stock upper shock mount so I made a support bracket and welded it to the new bucket thus keeping the shock in the stock location. The stock spring mounts on the rear must also be moved 1 1/2" inboard on each side of the housing. As I am not using stock lower control arms, I am not sure if they need to be relocated inboard to use the extra space available. Then it's on to the sheet metal part of the tubing. The left anf right sides are different and you will loose spare tire space. It's a lot of work for a small gain, but I expect that with the proper wheel back spacing I will get a 315/35-17 tire into the wheelwell of a lowered car.
