Previous owner has replaced the stock 17" Boxster Twist alloys with 18" Cayman replicas and spacers to fix the offset. We found the spacers were bodged together using tape and glue, and only two long bolts per wheel fitted!!
New spacers were fitted on the rear with genuine Porsche longer bolts, and the brake fluid flushed with ATE super racing blue to cope with the higher temps expect on track.
The car just requires an oil change now before our first track day.
