Well, that is the difference Les...if you the $$$$ to just turn your car into a true race car, and trailer it around, it certainly will be faster. I'm am an old street racer. So, even though I have a trailer, it has yet to be used, at least for my cars. I still like to play around with them, so, I'm just not into setting up suspensions and such. I drive them like I stoled them from time to time...but only a few HP mods for me right now. I don't ever see me going round and round, but do like to accellerate...lol...I think these cars do very well stock, against a lot of modified cars... and if we match their modifications, we would be superior in most cases...with matching $$$ for $$$... I have stated all along, you have spend 5-10 times what we have in these cars to match HP...and in some cases handling... They will be around for some time if the parts stay available
