in my opinion you would be hard pressed to get the Cougar competitive with the Camaro's
they are kind of the lemon in the pack in terms of performance but do look fantastic though
the Challenger has a better chance if you find that magic sweet set up
every class of car has it's go to car that anyone that is competitive will to straight to and in this class it is the camaro
shame really as it would be good to get a better mix on the track
the top cars in the American muscle car class that we race here in my club are all scalextric Camaro's
this is my 70 Camaro that I race


chassis weight is 79.5g's body weight is 17.5g's so total weight is 97g's
I could get the body a tiny bit lighter but felt it doesn't really need it
25k Nsr with NSR 12/34 gearing using the 17.5 mm spur
rear axle is slot it reduced center dia sitting in pro race ball bearing bushes
rear axle is braced to the motor with steel wire
rear wheels are slot it magnesium F1 hubs that have been lightened and fitted with NSR F1 ultragrips
stock front axle in the stock mountings the front wheels are the stock plastic rims that have been lightened as well
stock tyres that have filed/coned and coated with superglue
guide is ninco pro-race and slot it soft braid slot it lead wire
you will notice that I have left the valances on the chassis
I have done this to keep the body as light as possible as this is much much more beneficial to handling than cutting them off and gluing them to the body
the interior is a light weight flat type lexan with a stock plastic head for detail
and lexan windows
this is one very fast car and is a real hand full on the smaller tight tracks but is untouchable on the big wide tracks
doesn't stop me from winning all the time with it on either size track
I know this prob doesn't help with your build as you need to keep it pretty stock
but does show how far you can go with these cars and when you do they are one hell of a monster
it was keeping up with a very well tuned slot it Porsche GT1 until I de-slotted it
