Has anyone else done this? Just fitted a let with 6speed box and rather than lower the tie bar I have decided to lower the cross member which is bolts on to. Currently only at the stage where I have cut it off but going to weld a steel plate down each side then weld it onto that and also run some square tubing throught the cross member I think and also some reinforcing plates. This will drop the tie bar around 2" I think it was but also thinking about the track control arm, welding a plate on the under side of this and bolting the tie rod to the bottom instead of the top.
