Personally I made my own sub frame bushings and I like the idea of raising the sub-frame relative to the chassis since this, like the RS uprights in the front, lowers ride height but helps to preserve design roll axis of the chassis.

I noted that threaded bolt receivers in the chassis were very slightly out of square which is probably a non-issue, but it bugged me. It's no problem with the rubber mounts which allow for it easily, but I didn't like bending the bolt a bit. You can see in the photo with the arrows the slight offset.
So I sketched up a design using stainless spherical washers that allow for some motion and had a friend make them with his CNC machine.
The design also allows me to tilt the subframe with spacers if I want, but I didn't like the idea of less anti-squat geometry.

I tried the H&R Bars and they were too stiff. My car came with TRG 25mm front and 23mm rear and have to run lower spring rates than others with the RS bars. I may change to RS myself.

I will probably buy the RS bars and test at the track and if I like them I'll be selling the TRG's. I've already made my car 10 seconds faster over the past year at Barbers and I'm trying to get all of the time out of it. Driving on the road you will not notice a difference in any of the three bars (H&R, TRG, RS) and on the track you may notice .5 sec differece depending on setup with slicks. I've had all 3 bars but didn't change my suspension setup until now. Either way I will have one set of bars for sale if you are interested.

Started on the rear this afternoon, took awhile partly me trying to figure things out but it came together nicely.
Rennline and KW quality is great. Ira from Tarret Engineering was very helpful and a wealth of knowledge, highly recommend him.
Still need to figure out this ARB and Drop link situation but will finish the other side first.
Waiting for Elephants RS Uprights for the fronts.
