A good example of bad workmanship, rear inner brace bar had.....1 top bolt drivers side, no bottom bolt.( Due to bolt broken off in hole) Passenger side, top bolt had no fixing at all, and of course, there was no bottom bolt.I am still amazed at the things I am finding. Service history book, has written in it......Belts done.Would you rely on that?. Me neither, belts, water pump, will be done over winter. Car went very well at Spa, so yes, it is all worthwhile.
Next time you're on your way to Spa I'd suggest an overnight stop off and getting rs tuning or someone to give the car a good thorough once over. I'm amazed you're still finding these issues, but then not amazed as the guy who built it was a cowboy (Steve at SC Autos - thankfully no longer in business). It's good you're still enjoying the car though!
