What a strange project.
Took the heavy and weaker body (5dr), took everything out but left the dash - which weighs a fair bit - did this all to an 8v - not exactly the most powerful golf ever built - and did this with a big bumper version as well.
If memory serves me correct there is 1200kgs on a the big bumper 5dr vs 1000kgs on a small bumber 3dr.
And if you want a track day car - why a Mk2? Mk1 weigh so much less!??
Very odd.
