I'm definitely going to purchase the FE4 SS front bar (23mm solid). I believe the part number is 22875934.
However, I'm on the fence on what rear bar to get. Initially, the plan was the ZL1/1LE bar (28mm solid) to keep the +5mm bias. I see the part number as 22786260. Now I'm thinking about getting the Z/28 rear bar instead (26mm solid; 22812943).
If I'm not mistaken, the OEM FE3 suspension came with tubular 23mm front & rear sways and the car was very compliant. My fear with the 28mm bar is that it won't be soft enough to make a difference compared to the 32mm bar on the car now. If the car was good with a 0mm bias stock from the factory (with stiff Xa coilovers), I feel like a +3mm bias along with the new FE4 rear mounting points should make it easier to push without losing traction.
Thoughts? I'm just thinking aloud.
