I have the Blue Alloy/Carbon Fibre Front Bulkhead on my S2 & I have 100% Steering lock on mine

.............its the optional Blue Alloy Steering Assembly that you can buy, that seems to be manufactured incorrectly, causing Steering lock issues.
I have cracked the 2mm thick Carbon Fibre section of the Blue Alloy Front Bulkhead though..........I ended up having some 3mm thick Carbon Fibre replacements made at Fibre-Lyte, which are far stronger & look alot better, as I had them shaped differently
