I was wondering (since the installation of sways is so expensive) what you guys think of harder bushings for the stock sway bars.
1.Can you install them without working half a day on the car? 2.In combination with coilovers/stiffer springs, wouldn't the body roll be reduced enough? (I know that's subjective..) |

It is so expensive, because you basically have to drop the drive train out of the car, the sway bars sit above where they sit on the chassis on most cars. 1. Absolutely not, in fact I think turner is prob the only shop that could get it done in 6-8 hours. If I was within a few hundred miles of them I would have them do it. It is a serious job and a lot of components have to be braced or considered. I think a good indy shop will take 10-12 if they have not done it and are being cautious. 2. No, the car exhibits to much roll, and puts a lot of stress on the suspension. May be fine for road driving, but track, autocross no way. In fact a few people have broken there coilovers from the stress. |

Custom made them at my shop, it helps to have a few million in cnc equipment. I wanted really strong links and joints since for some reason these cars exhibit a huge amount of load transfer and forces on the suspension. I am trying to reduce this as much as possible to let the suspension do its job.
I will also be making some rear lower control arm bushings soon, since I toasted mine tracking the car. But to be fair my car is heavily modded and when on the dyno was putting out 410hp and 500ft pds of torque at wheel |

What ever happened to the Hotchkis sways? After mid-March post saying they would be available at the end of April, this thread has gone over to an H&R discussion. The Hotchkiss web site has no mention of swayers for the F22 chassis.

As far as the end links go, I think many off the shelf applications would work. My company makes rapid prototype parts for the military, so spitting out end links would not be viable. |

I appreciate that, and i was just busting on yah I am really interested in that 500 ft lb of torque that must break loose those rear wheels like crazy.
Are you running 50/50 meth or 100% -Paul |

There's a member on here that got them installed by Hotchkiss but your right the site doesn't have them listed for our car. I'll find him and ask.

I have a prototype set on my car from Hotchkis. Have you tried emailing/calling them directly? It's possible their website is outdated

Yes all the way to 3rd. 50/50. I only use the meth at the track (road corse). Cools the intake, and adds power, win win. Only downside is I have tore up the rear end bushings, but that could be too much drifting. Really could not imagine the car without it anymore. |

For install, you need to brace the engine from above, unbolt the front subframe, lower it down and pull the stock sway bar out. Then put everything back together. The rear is pretty much the same with exception of bracing the engine obviously. In the end, it's a lot of work, but worth every penny. The car has very little roll at this point and turn-in has been greatly improved. |

So, a little more feedback on the sway bars. I've had my H&R bars installed for roughly 2.5 weeks. I can honestly say, is the BEST upgrade that I've done to the car performance wise. Initial turn in is amazing. I've gotten rid of the excessive body roll that I was experiencing before. And last, the rear end will actually start to slide mid corner if coaxed enough.
Again, I'm truly impressed with the characteristic change made to my car and would highly recommend these to anyone who autocrosses or tracks their 2 series. Well worth the install "hassle". |

Just gonna leave this here for anyone in the future so they don't deal with the crap I've dealt with this weekend. The 228i bar WILL NOT fit the M235i. There is no bend in the bar for engine clearance and the bar will contact the engine on an M235i. I found this out the hard way by though some confusion on my part and ordered a 228i H&R bar thinking they would work. They don't. I'm hoping I can get something sorted out with a replacement from Turner, if not, I'll probably be selling a 228i bar in the very near future.

I'd say that's exactly the reason to try a slightly softer setting for the front. Usually, too stiff front (relative to the rear) results in understeer as you need some body roll in the front for proper turn in and cornering. I'd try softening the front, if that turns into oversteer I'd use adjustable end links to set it just right (stiffen a bit but not too much). In fact, I'd use adjustable end links in any case to dial the front to a sweet spot (or, as an option, you could try gradually softening the front via end links changing their length while still connected to the stiffer setting on the sway bar). I'd try.
