Brilliant skin pack! For those that are unsure the touring rules in the 80's ran to Grp.A and a 2/3 tier class format hence why the Ford is faster then the BMW is Ford was Class A, BMW Class B but races we're run like a endurance race with pitstops etc
It's why Ravaglia won the overall '87 season as he scored more in class points then Ludwig even though he won more out right races
Apologies for high jacking your stuff but some of the comments stired me
so do not rate this skinpack for the car performance balance
sacondly, and even more importent i dont think that ford it's to fast
