The back end will kick out at autox on throttle lift, while turning hard... but even during aggressive driving on the street, it's nothing crazy as long as you stay on throttle.

I'm asking in regards to handling on a road course, not on the street. This bar is a bit overkill for someone that doesn't track their car.

Open track days is this Friday and I'm on the stock RSB, so I imagine I will be picking one of these up very soon.

Yep, I'm running those Hoosier slicks. I'm going to keep the bar on the least stiff setting for a little bit. I might change it after the Toledo autocross. The course is normally pretty fast at Toledo so I don't want too much oversteer. I would like to get the new JBR front sway bar once it's released and I'll probably use the stiffest setting on the rear sway bar with the front bar on there.

I agree, this bar is definitely overkill if you don't do any track/autocross. I'm hoping to do a track day at Mid-Ohio in a month or 2. So I'll be able to comment on the bar's track performance after.

Well finally had the opportunity to put the Fat Boy through it's paces this weekend @ Mid-Ohio at a PCA event where I was instructing. All I can say is that if you track your car, this bar is a MUST! Mid-Ohio is a very technical track, with high speed turns, elevation changes and this bar handled everything that the track trew at it.

I placed the bar in the middle setting for my sessions and it did not disappoint, actually exceeded my expectations. The car felt like it was on rails, throughout every section on the track! Coming thru turn #1 and heading into the Chicane ( turns #2 & #3 ), the car was firmly planted and rotated like a champ. Heading into the Keyhole, again, the car rotated perfectly and set me me up for the long back straight, where speeds hit between 130-140.........settng up for the entrance to Madness (esses), the car remained settled and balanced coming up and over, heading for the Honda Bridge and Thunder Valley.

Again, the car rotated perfectly, throughout the entire course and with every lap, I had more confidence in pushing the car, lap, after lap, session, after session. I would highly recommend this bar for anyone who spends any significant time auto-xing or particpates in HPDE's! If it can handle Mid-Ohio, it can handle any Road or Auto-X Course!

Well worth the money and stood up to a lot of hard driving!

Thanks for the review MOCO MS3, this solidifies my decision. Are you running the stock end links with this bar?

I am running Tri-Points Adjustable End links. Tri Point has been sold, but I know the person that designed them, he may build more.
