Camber question

[dnova89]

Hey folks,

Well I'm back again to ask yet another question. I just wanted to say I really appreciate everyone being so nice and giving me detailed answers. I see a lot of hate bein dished out to people on this forum, and I'm glad that I'm not one of them haha.

So I just ordered up my AST 4100 kit, vorshlag camber plates, rogue engineering polyurethane RSM's, vorshlag RSM reinforcement plates, and hyperco springs. For wheels/tires I got TRM C1 15x8 with 225/50/15 BF Goodrich G-Force Sports. I think I'm aiming for somewhere around 400f/500r in terms of spring rates. I wanted to lean on the softer side since this is my first aftermarket suspension EVER. Call me crazy, but I've done tons of research on all the different suspension setups for e30s, coilovers and non-coilovers, almost every brand out there over the course of a couple months. I was about to go with the TC Klines, but I found a deal on the ASTs I could not refuse. I already paid for it, and I'm happily waiting to receive them. If my seller can't get those rates then I may have to go a bit stiffer with 500f/650r. I'll update it once he lets me know what my options are tomorrow.

First of all, I wanted to get a rear camber kit so that when I'm done installing everything and go get my alignment, they can do the rears as well. Any recommendations for some good ones? The only one I'm aware of worth looking at is the ones IE offers. I wanted to see if there's anything else out there, or if anyone can vouch for the IE's.

Second, I wanted to get some recommendations from you guys on what I should tell the guys at the shop what I want my camber set at when they do my alignment. This is going to be mainly a street car with lots of track use. I plan to go to the track anywhere from 6-10 times a year, it really depends, but I'm serious about getting better and I want to get as much seat time as I possibly can. I don't know if camber will have any impact on comfort, but I'm more concerned with my tires wearing evenly and performance. I can sacrifice some comfort, but like I said it's my DD as well as my track car so keep that in mind. With that being said, what more information can I provide you folks to give me some good advice? Looking for specific camber angles rather than ranges, as I don't want to tell the guy at the shop "oh just go ahead and set it anywhere from -1.5 to -1.8" lol. So if you have any experience with certain camber angles as opposed to other ones, please inform me of your conclusions!

Thanks,
Darius

The IE weld in camber and toe adjusters are far better than eccentric bushings, which is the only other choice I know of.

I think you'll need stiffer sways. A 22/19mm set should work well.

The tires used determine what camber to run for the best handling. I don't know how much camber those tires want, but for a dual duty car I'd suggest front settings of zero toe and 2.5 deg camber. For the rears try 1/16" toe and 2 deg camber. That should result in good handling without terrible tire wear on the street.

there is a third option - shorter subframe bushings to raise the subframe up into the car 12mm. This reduces both camber and toe closer to stock (it's like raising the car 12mm). AKG has the skinny but I think you have to call. Maybe not a bad choice if you're replacing subframe bushigns anyway. Of course it's also not adjustable.

if you like, you can also invert akg poly subframe bushings(make the top the bottom and the bottom the top). it will raise you about 5mm as opposed to 12mm.

Weld in kit for the rear is the way to go. Massive also sells soild rear subframe mounts that raise the rear subframe 12mm. I have it on both my e30's. What's the tread wear rating on those tires? 400/500 spring rates is soft for the rear. I would run at least 400/600 is you want a nice street setup. I run 500/825 on my 89 325i DD.
