Last weekend I ran an hpi supra and after my first tank was done I was wishing for my protoform mazda or stratus or dna because though the hpi bodys look good they don't handle the same at all. With the supra body on I was really bashing any and every car I cmae to run with though I was NOT trying to smack their a$$es. With the protoform you will have a lot more turning control and for me strait line improves as well. Hope this helps. Hpi=shelf queen
Protoform=race car
