Rear M Roadster Swaybar Group Buy???

[RidingSimple]

With the talk of the 28mm front bar group buy, I was thinking what about the 18.5mm factory rear bar that the M coupes and Roadsters came with stock?

Tischer has them listed as $130 msrp, and their price $109. I think a group buy with the bar itself, the brackets, bushings, and mouting nuts/bolts would be a sweet upgrade for the ti.

Thoughts?
Tischer BMW?

I'm in!

Is there a particular handling characteristic that you are trying to tune out of the car with a larger rear bar? I wouldn't want to upgrade the rear bar as that will make the problem of the inside tire lifting that much worse.

Well, I only have the stock 14mm puny rsb, so I would at least like to upgrade to the 16mm sport bar, and for the same money, why not do the 18.5mm roadster one? I'm not thinking that will be so stiff as to make the car lift the inside tire. Thoughts?

My car has Bilstein Sports and H&R Race.

It seems like the wimpy flange the sway bar attaches to is not strong enough to lift the tire anyway. At least from the looks of it. Does the M roadster reinforce that flange?

The bracket is the same on both cars; doubt the bracket could be welded any better on the MZ3. I had MZ3 brackets welded in, since one broke. Adding those adjustable endlinks and reinforcement tabs is a nice touch.

On an autocross course a Ti can easily lift the inside rear tire with the stock rear sway bar.

In my car this would cause bad power oversteer. Once I changed out the rest of my suspension for coilovers I never had an understeer problem so I never needed a larger bar in the rear.

Bigger and stiffer rear bar does not always equal better handling. You really need to think about how everything will work together and what changes the increased rear stiffness will cause.

On the street you may never notice the rear tire lifting, and the rear bar will make the car stiffer, which may give the butt dyno impression that the car is handling "better."

Yeah, that does make sense. I am definitely going to purchase a 28mm upgraded front bar, and one I get the autocross wheels/tires mounted, I'll do a few runs to see how things work out. If I find I need more roll stiffness, I'll upgrade the rear bar....and to a X Brace, and a front strut bar....and...and hehe it's never ending.

We now have 3 different group buys going on.
One is a year old, another is almost a year old.
And that is just the ones that were bumped.

If a group buy doesn't pan out before the end of the year, I'm going to put a ban on group buys. They don't appear to work. Perhaps there will be more luck on bf.c when you can get more involved.

The LudicrouSpeed Eibach sway bar Group Buys all one Group Buy. The first one never really ended, and was never meant to end. That's why I continued last years thread instead of starting a new one.

Each time there is a batch of 3 or more orders, a Group Buy can be made. The only difference to a year ago is that prices went up, so there was an adjustment to that.

The other, "front only" GB from a while ago was also part of the same GB for the kits.

The last round of Group Buys through LudicrouSpeed sold 4 bars to different people, not including the two I bought for myself. They do and are working. Ask people who have received their bars already.

LS and I have nothing to do with this (the M Roadster rear bar) Group Buy.

I'm just talking about group buys in general.

[RidingSimple]

I did not realize this was a big deal.
Delete the thread if need be.

It's not a big deal.
I just don't see group buys being productive. The other two have been going on for a year.

[gimp]

They are productive if people get their stuff at a good price. At least five people so far have (in the other two that have been going to for a year).
