The mod factors for suspension and aero kind of knock me out of TT5 as my adjusted power to weight would end up at 16.00 lbs/avg whp (vs the standard 14.00 for the class).
That said, the class should be a good fit for those who haven't invested in aftermarket aero or heavy duty suspension mods (remote reservoirs, control arms, etc).
