M4 S55 Crankhub Fix

M4 S55 Crankhub Fix

Tim's M4 came in for some much needed engine maintenance.

This week we carried out the following work:

Crankhub fix with Insane 4 pin crankhub

ACL rod bearings

Exhaust camshaft alignment

This has now made the 90k mile S55 engine much safer and more reliable to use on track, as we did at Snetterton the week after!!
