First and foremost, car will be mainly street use, I hope to do a lot of autocrossing but I'm probably 5 years away from that. I've been doing a lot of research in rear suspension recently and it looks like every system has it's trade offs. I'm aware leafs can work well but they lack adjustability. I know DSE makes great products but cutting a bunch of holes in my car for a 4 link does not interest me. I looked into IRS but the only bolt on solution (heidts) seems like show suspension and has exhaust routing issues I don't like. art morrison is great and proven but requires me to cut up the entire rear of my car. Anyways that brings me to my current solution, a torque arm. From what I have found it gives me the ride height adjustability I want for my dumb requirements and seems to be my best overall compromise of what I want to do with my car (exhaust routed a certain way, be able to easily adjust ride height with shocks...perform well) I have found 3 main people BMR, Speedtech, and Chassisworks From looking at it, it looks like this will force me into a rear end so I will probably have to buy a ford 9" and will look into a full floater as it will be stronger, and safer than building up my 10 bolt. (and means it will take longer for my car to be on all 4 wheels again) Anyways, does anyone have experience with these set ups? BMR seems to be the most affordable which is nice, and comes with a watts link, the other two makes that an optional upgrade from the looks of it which means more $$$. Shocks on BMR are sold separately. Speedtech looks to be about middle of the road in pricing, I know people seem to like their other products so I can't imagine this one is bad. Both speedtech and BMR look to use viking shocks so it will match the front of my car Chassisworks seems nice, and the most expensive out of all the options, the real main benefit from them is they they're about 20 minute drive away from me. I'm also sure their stuff is fantastic, but what I really want to know is if it's an extra few grand fantastic. (I can't tell if that rear axle is sold separately, I think it is) Seen a lot of bad customer support reviews from them though which is concerning with the amount of money that will be spent. I intend to weld all of these options to my car to give them the most strength that I can. so thats where I stand, I'd like to know everyone's opinions. Not really interested in other setups unless you can provide strong arguments for something else that doesn't require me to obliterate the rear end of my car with a saw.
