I plan to drag race (Stock events) my Z that I have not raced or even hardly driven since I purchased it. Our rules in Saskatchewan state max 3/4" lug track allowed. I have purchased a very good condition used Arctco rubber track for the job. Thought I would post the conversion as this is fairly extensive to do converting from a unique cleated 3.29" pitch x 112" to a 2.52" pitch x 121". The skid will need to be totally modified by widening the rails spacing from 7.5" to 8.875" c/c and lengthening them 4.5". I have acquired used Z rails and other parts to do the mods. Needed the upper return rollers on the rear swing arm and now have a good used set. A bit worn in the bores. The rear swing arm looks to be a custom steel replacement and I do not have the aluminum swing arms for this. If anyone reading this can help out with locating the aluminum swing arms I would be grateful. I will start out by posting pics of the rails. Needed straightening on a press first and then 4.5" rail extensions prepared. As I cannot find original antistab parts for the rail nose I purchased an aftermarket antistab plastic part that fits the rail profile excellent with minor rail modification to accept them. More to come as I progress.
First photo shows rail extensions ready to be welded.
Last photo shows the original worn out antistab on (upper right). Rails both modified to accept the new antistab (lower right)
