Thanks for all the comments
Unfortunately not much to add since the car is still a daily driver due to unforseen events with our other car, but I will be sprinting this year in the road going production class, MSA rules state full working interior so theres not much I can strip out of it, only sound deadening and carpets. No need for roll cage so budget can stretch to polybushing the car.
I now have a garage that took me and my mate a few months to build, so these cold dark nights will be spent chipping away at the sound deadening, not looking forward to that much!
Just looking at the top pics and the engine bay is out of date - I have a larger MAF tube to cope with the increased airflow of the 20g (the previous setup was being maxxed at 380HP) and the aircon is gone now
