seems like a tough field, the only rwd car i can see that you may have a little more power than is matts rx7 as he is N/A engine this year but then his car weighs just under 1100kg.

What have you done to help with handling as you maybe down on power but maybe you can make it up in other ways.

Suspension is the main one as you will need alot done to catch up with the modern double wishbone suspension on some of them cars, also what downforce are you adding to the car as alot of them cars run big proper wings, carnards, flat undertrays etc
