I do some caveman level alignment stuff myself; Usually I'll get my settings done by someone with better measuring components. I'll admit that I am a huge suspension dork, so I end up asking for pretty specific things when I get it on a rack and have a professional at my disposal. My other project is a road-course Chevy Vega GT. While it doesn't suffer from the typical super weird GM camber gain front geometry, it was optimized for super tall sidewalls with really crazy slip angles (typical early vintage car). In fact, there was enough built-in slip angle compensation in the steering geometry that it was actually designed to toe in after initial turn in. Really strange to discover that sort of thing. I ended up fabricating a significant modification to the spindles to move the outer tie rod ends out farther, and converting the car to a rack to get better ackerman. Now it's got lots of extra ackerman. The rear suspension in that car is something I fabricated from the Miata design: Double wishbone IRS. I modified a stock Miata crossmember to accept a Turbo II 8" center section from the RX7. I also included a rear-mounted alternator that runs off the pinion instead of the engine as an accessory. FUN! I've been very impressed with the solutions BMW came up with for the suspension geometry. It's just plain so vastly superior in that way. I just realized I didn't answer your question about the subframe bushings: Yes. I did install some I purchased with the same kit from Ireland, along with control arm bushings too. SUPER squeaky, even after ladling them with silicone grease. I routinely lift the car up and just squirt more in there to mitigate the noise for a while. That said, the rear suspension acts WAY better. More accurate and predictable. The thing I've noticed now is how much the engine and transmission mounts slop around. I guess that's next. LOL! Never ends. Oh yeah, I forgot to mention I creeped your site a bit. Pretty cool! I'll likely be talking with you soon enough. Last edited by Nix328ti; 09-14-2016 at 10:18 PM. |
