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... |
