Yes I had seen a post somewhere regarding the cat arms and have some left over from a cat I recently sold so all good.
Used it for the first time last night and it was awesome. Lapped quicker than I could get my b max to lap,suits my driving style as it Is a proper hooners car and appears to like being thrown hard into all corners!
Very impressed but broke a front bulkhead as I hadnt done the pin brace mod!mind you I did hit it hard!
All in all very impressed.
