the best cheap mod for a day, remove any belts you don't NEED. I take off my a/c belt the second the temp drops 75 degrees. I sometimes take out the power steering belt but i don't recomend it, it makes torque steer a b**** on the track. For tires, if you want an AMAZING set of seasonal tires, get BF Goodrich G force T/A KDWs. Honestly, they removed 80% of my torque steer. but expect to pay $125 a tire online, or $140 from a local shop. Taking out the passenger seat is easy, do it. your best bet for fuel is to have 1/2 tank of 87, and use your choice of octane booster, mix accordingly.

 

I second removing the belts and all the easily removable stuff out of the car, but octane booster... what a waste of money...

 

get a 5spd fing02.gif

 

amen to that, but I doubt he'll get it for under $200
