GY3 the key word is 'aftermarket'. A gent back then would not consider paying for any upgrade that didn't include horsepower. Brakes? leave them and just hope it will stop after 1320 and backing them off to have less rolling resistance. This car is a time capsule. Is it unsafe in people's minds now?... yes absolutely. The people saying they see the same type of stuff today that runs at tracks shows 'it aint pretty, and it's probably unsafe but it's what I have and I will try and make a few hits' Would I want to run next to that car?...No! The thing for me is the nostalgia. It's cool and brings me back many years ago.
