FD3S Tuning Tips for New Downhill B Class?

I do love my MR-S, I was thinking of learning how to alternate through two different cars. As I was thinking a more challenging car to drive down New Downhill, I decided an FD for the downhill. My MR-S was not tuned by me. My buddy ILLMATTICKNIFE tuned that car for me to learn a proper line, throttle control, and braking lines. I want to tune this car myself, but I do not know how. I attempted to tune an FD, but kept getting 4:53 average. For some stupid reason, I sold the car... I just need some tips on this car. I will not resort to aero for this tune. P.S. Sorry for this long paragraph I typed. I just like typing :Pasdfghjkjl;'

It has been prover SPORT suspension is the fastest FD setup in B class. Which makes your life easy, tuning wise. Slap on some race tires and get it as light as possible. Just setup your tires, alignment, rollbars, and diff. and you're set!

Sport springs and stock transmission with pretty much race upgrades to everything else. Don't forget to turbo glitch the engine, upgrading the intercooler might come in handy too.

Will this be a B class still (even with the race tires?). Also, I am thinking of putting an aero wing on the FD to stabilize the car. I know that it is looked down upon the community, but should I?

You won't learn car control if the wing is doing it for you

The FD is a car with extremely wide tires, it shouldn't be a problem without aero.

Yeah even i can keep it straight mostly and i SUCK with fr cars

There's only like 2 things you can tune with the FD when in its optimum setup anyway. The tune is on the Tuning guide if you'd like to take a look
