I haven't checked my bushings after the last open track day at VIR from earlier this week. I had some noise coming from the sway bars, but nothing like what I experienced during the SCCA Time Trials when the bushing split. There was tons of noise and massive oversteer when the front bushing squeezed out. I'll report back after I inspect the bushings, but my feedback to BMR is that they aren't "fit for purpose."
There is a ton of potential benefit from having adjustablility in the sway bar rates, especially if you are running a 305 square set-up like me. If you can't trust the hardware, then it's worthless. FYI, I came in second place by .182 seconds.

yeah, unfortunately some of BMR's products and instructions aren't appropriate for road course use. Cars and coffee crowd cruising and driving to Wal Mart are the only thing some of their products can actually do. They need to review the directions on all of their products as GM's torque values are not used in some cases.

Clearly, if a key part responsible for a car balance at high speeds breaks, it is completely unsuited for the purpose not to mention: unsafe. Good to see first hand feedback from track going folks to inform the community here.
Generally speaking, our community would be better off if we posted any issues sooner vs later and with no reservations. Imo it is good to support aftermarket industry, but only if they make quality products that work as intended and as advertised. Otherwise zero progress is achieved and the wallet needs to be emptied again. Cheers! |

Regarding the BMR swaybar bushings splitting. That the first I've seen anything like this.
I've got Hotchkis swaybars and the bushings that come with them. If it were me I'd lookup some circle track suspension vendors and see what they are using. If mine do this I'll find some bronze bearings and get the local machine shop to machine up some aluminum cradles to hold the bearings.

I got mine yesterday and installed it with the supplied bushings. I autocrossed the car today. So far, so good. I'll keep a close eye on the bushings. FWIW, the Hotchkis and AFE bars appear to come with the same bushings, but supplied with machined brackets instead of the stamped ones BMR provides. I'm not sure they should be any better, because that bracket still doesn't look very beefy. If mine have issues, I'll see if those Ford-purposed ones fit our stock brackets.

I will also say that the one time i went to the drag strip last year i completely unhooked my front bar. Idk how people do that as the car was scary and almost undriveable on the street. I could keep it on the strip but it was very floaty and I will definitely never ever do that again. |
