Yep. I like the Blowfish hooks better.
Thanks for sharing your experience with the 23mm bar.Also switched to a 23mm RSB and it definitely makes a big difference in cornering.
The first thing that I noticed was a little more understeer, especially in tight, slow corners, but part of that could also be the perception of steering response delay going from 35 AR tires to 40 AR tires.
However, with a stock Boss, it can be as simple as changing the rear bar to a 24mm GT bar or any other smaller rear bar up to removing it completely.
Thanks for this post. I am going square as well, but am still waiting for my 18x11 wheels to be delivered. Have a 23 mm RSB ready to install, but the FRPP rep with some knowledge of the Boss suggested that I run with the stock sway bar before switching to the smaller bar. Any thoughts on this setup? Were you running the stock bar with a square setup before switching to the 23 mm? Oh yeah, installed the T springs this winter. Let us know how your next track event goes. Thanks again.
I've long suspected that the 24mm GT bar would come closest to neutral balance when used square with Boss and most of the OEM spring sets. The spring rates and ratios front to rear between the Boss and GT are relatively close. And if it doesn't quite balance perfectly, it might be just a bit loose, and what some drivers would be looking for.
I'm only running 18x10 square with 275 NT01s at stock ride height so I can't help with the rubbing issue, but FYI I am really enjoying the balance with 23mm sway bar for the track; 22 should be nicely balanced as well. I agree you should try stock bar first, at least on the street (carefully, don't go full throttle exiting a corner or trail brake too hard), to really feel and understand the change, but you will want the smaller sway bar for the track. Are you running a different tire/wheel setup for the street?Any 2012 Boss owners with fitment experience running Apex 18x11" ET52 wheels with NT01 305x35 out there? Have stock dampers, Boss T lowering springs, MM CC plates, 2 degrees negative camber.
Thanks for the feedback on the RSB.

I'm going to suggest cutting only some of the bracket away. Leave the flat part that the b/s contacts in place so you don't give up all b/s functionality.Yes, I do have an adjustable BMR PHB.Received some good advice from Apex today. The bump stop bracket may be in the way, but only when the axle is unloaded. Use a jack(s) to load the axle, then mount the wheels. Optionally, the bracket can be removed, its spot welded in place, and relocated. A kit exists for relocation. Vorshlag Racing talks about removing this piece in a Utube video. Of course, small spacers can be inserted. What size spacer works well for the fronts with stock dampers? I have a 25 mm so clearance is not an issue, but the tire juts out at least an inch from the fender.
