<![CDATA[crappy e36]]>Well, ive got a few questions and need some help making my e36 cool. First, the rear suspension feels really soft and loose, as in the bushings feel weak, where should I go to find either better bushings or control arms?

Second, I put some h&r lowering springs in all the way around but the rear sits just as high as it did before?! Why is that? Haha I hate how high it sits in the rear.

Third, is anyone running a 7200rpm limit? I want to but I'm worried that the m50 w/vanos can't handle it with drifting seeing as I'm @ rev limit literally all day on track days.

Lol. I feel like the rtabs are pretty small. Like 1.5" od or less. 

Man I lied. I was going to build these, but I thought they were the same as the e30. I need e30 rear subframe bushing and rear trailing arm bushings. Anyone want to measure some? I have a rear subframe I guess I could measure? Paying 300$ for 30$ worth of delrin is crazy talk to me.

I will take at least one set, let me know the price!

Haha I'm asking how much I should charge for them, as I have no idea.

When does production start? Haha

I'll build some this week! They will be Delrin.

So... I can't do it for absolutely free.

Price? They shouldn't take too long to machine!

How many should I make?

Might order stock to do a good batch of them.

So. Drill .975 or something close, and press in a 1" alum round stock with a 12mm hole, and exactly 49.25 tall?

Got the dimensions, here's a sketch i made.  Didn't have time to draw it in CAD.  It has to be a split design for assembly.  The poly ones have an aluminum sleeve through the center, the bolt is an m12.  My poly ones have a sleeve that is about 1" O.D. through the middle, now that I think about it, the sleeve is probably necessary because there needs to be rotation when the suspension compresses and the mount bracket locks down on whatever is in the center.  If you didn't have a sleeve then it would clamp down on the bushing and the rotation would be forced to happen at the O.D. of the bushing against the control arm.

Looks good to me.

Yea its the shocks. I believe they typically run maybe 5" of travel and after lowering itbon the shock you decrease it further.

I've never heard of track cars having 5" of travel, even with rally cars that would seem like a lot. My coilovers on my e34 travel about an inch and if I adjusted them for 5" of travel they would basically ride like stock struts except with dampening capabilities.

Usually the race guys go to a true coilover in back for increased wheel travel and to use a tube style LCA.

I would think wheel travel is increased to a ridiculous amount with the stock setup in coilover form, what acts as a limiter with that setup? The shocks?

Just curious what benefits you think you might see out of a true coilover in the rear.

Easier adjustability, better limiting of wheel travel, I just think the e30/e36 rear suspension is outdated, I mean every other car in the world has struts or coilovers at every corner for a reason..

Definitely, I would reinforce the rtabs and anything else I can in conjunction with the subframe

AKG motorsport has excellent prices and the parts are good, they are what I used.

I will get the measurements.  The only problem I can see with a solid mount is that it is not a purely rotational force.  I would think that it would be a good time to weld in rtab pocket reinforcements.

There are "true" rear coilover set ups out there but they are ridiculously expensive.  AST and Intrax are the two that come to mind.  When you do it just make sure you have some kind of reinforcement on the strut tower beyond the normal strut tower plate.  I looked into this before I went with my FK's and switching to the true rear coilover will increase the loads on the towers by quite a bit.

Yeah, ill have to reinforce the tower and the spindle but itll be worth it to have a real coilover setup.

And if you guys could machine solid rtabs that would be AMAZING.

Rowley, get machining!  I could measure the ID of the trailing arm hole tonight, mine are in the basement with bushings out.  I can also check the dimension of the ID of the sleeve that goes through the poly.

Honestly that would be amazing. I can build them in minutes, and we have delrin in stock. Brothers gonna be stoked about this haha.
