Data from my swap manual, rear suspension section: Sway Bar--------Bar Diameter Standard ti-----14mm Sport ti / 323ti-----16mm M Roadster------18.5mm M Coupe--------19mm Based on this, I'd say the front is 12.5% stiffer than the stock ti part. It's pretty befy, but I don't know the diameter. 26 maybe? It's long, so it has to be pretty beefy... Because the M3 one is shorter, it is actually smaller diameter and stiffer... |
