If you take your time and think out your mods, tuning is much easier. My E36 M3 was pretty much un-drivable for a while, till I spent a few hours tuning and testing, now it's one of my fastest A Class cars.

As a general rule of thumb, I do race suspension, weight reduction, race slicks, widest tires, aero, and then power mods in that order. I always max the aero out, any speed you lose on the straights you make up in corners.

My friends and I just started doing our own spec Miata races, and it's the best racing we've had, its a blast!

 

sounds awesome, i do the same too. i do a time trials in the top gear test track with my housemates haha. my E36 M3 is also one of my fastest A cars. I just need to sit down and work it but too much to do and so little time

 

My favorite cars are the lightest ones..but red over fwd. i usually don't even do power mods lol. weight reduction, tires, suspension, aero. is usually the order i go with power last.
