Put the JBR 250 true torsion RSB in this morning. The brackets it comes with are real nice and beefy. It took a little more effort to put the brackets in due their size. A lot of clearance for the upper bolt is lost. I used a wobble socket and normal sized socket, as opposed to the deep impact socket, to tighten the upper bolts down. I cut off the open end of a 17mm ratcheting wrench and put it in a pipe to get the end link nut to the proper torque spec.

I have the RSB set to the middle option. The car feels better coming around corners and has significantly less body roll compared to the CS RSB Ver.2 I previously had. It's probably overkill for a daily driver and for someone that never AutoX, but because Racecar! I'm looking forward to seeing how it handles a cruise over the Mulholland Highway next weekend.

Here's pic to the JBR RSB vs a CS RSB Ver.2:



Here's a couple pics of my 17mm wrench and pipe:

what is that little bolt with the cp on top of the bracket for?

Grease fitting.

Also referred to as a zerk fitting. A grease gun fits to it and make's for a non messy way of greasing the bushing.

Thats what I thought, I guess its just a matter of can you reach it without removing the bar all the way ( in my case I'd have to lower the sus again prolly)
