These one piece reinforcements allow easier positioning and welding than multi piece kits.
Welding the trailing arm pockets is always done from underneath. Having the reinforcement made from one piece removes some of the hassle.
The football shape for the rosette welds were decided after consulting with a professional welder. They allow plenty of access for the mig torch.
Price is per pair of reinforcements (enough for both trailing arm pockets).
These will only fit E36 sedans and coupes. Will not fit 318ti.
