Thanks for the nice comments and exhaust info, i will add the balance pipe before the mufflers, it will run across above the back of the bell housing. As for my rear uprights, my engineer feels that he can skim them out to specs. Failing that I may just revert back to the original Subaru housings. They could easily do the part even though the toe control would be `different`. Terry, I did not cut corners with weight and built them from 4mm plate which i had folded to the shape and then cut and ground them to fit. The job would have been easier if I had used 3mm for definite. I turned up the centre bosses and then welded the laser cut brake mount which included a ring around the boss for accurate location onto a step cut on the boss giving correct caliper location, all that was easy! Big mistake was underestimating shrinkage from the welding. If i did this again, i would change my process to only roughing out the inside bearing area and then making a jig /plate that supported the entire assembly in the lathe and AFTER all the welding was done, then do the final bearing and seal cuts meaning no shrinkage. I will now make up that jig plate and hope that there is enough meat to work with. It will mean some careful set up before cutting.
As for weight, try 4 kg each versus the origional Subaru ones at 3.5kg. I think also that I may in the future look to other drive systems such as Nissan because there bearing bolts in, meaning that welding fabrication is not so critical. I can not change now because i have my wheels on hand.
Other news is that I have sold our McCopy mk11 Lotus! V8 as it did not get used during the winter and Carol and I got burnt to a crisp last summer from the sun and wind burn.
First to see bought it so I am now looking to buy a nice MX5 where we can choose the exposure to the elements.
Off for a few days r&r now.
