Yesterday I was testing some standard ffs. Honda integra type r touring car, if race cars are ok, lots of front grip understeers only if i give it to much gas. Trail celica SS-II, very sharp turn in, sometimes make me to confident and understeer from coming in to hot.
good video Orido I'm subbed
Thanks Flex, you can also try some rarely used FF, like Fiats, Opels, or most standard Japanese FFs ( Toyota Sera, Nissan Bluebird, Honda Accords, etc ) sometimes you could find great car that suits your driving style when least expected.
Just fit them with SH tire and run them stock, if they feel good on braking and corner entry ( not much understeer ), and can be built to at least 430PP, then you can invest a bit more to find if they are comfortable and competitive enough for you. The next step would be reduce weight if it's weight more than 1300kg, add power up to 220HP, aim for 410+PP, run some laps, if the car can get into 1:45s easily, then it's good sign.
My general base tune for FF :
Base PP from 410PP for starter when testing.
Suspension :
I always ran higher rear than front in ride height, usually by 15mm difference.
Spring rate : 2 times more stiffer at the front than rear, the stock rear spring full custom value is a good baseline. Increase the front spring to twice the rear. Example : 10.4/5.2
Damper : run lower compression front than rear, and have the extension at least 2 values higher on both.
ARB : I always use 2 values lower front than rear, example : 2/4, 3/5 or 4/6 - seems to work, but rarely I will need the opposite : 4/2, 5/3 etc.
Camber : run close to 1.0 at the front and double that on the rear, example : R 1.2 F 2.4
Toe : + at the front and neutral or - at the rear, the sweet spot hovers from 5 to 20. Example : F +0.07 R 0.00/-0.07, F +0.12 R -0.12
LSD : run low initial at 5 to 8, run accel from 10 to 15 and braking from 7 to 18.
These are similar to my Mazda's video I posted. Also try not to run too much torque, close to 250 ft lb /ft usually burn the tires easily, balancing HP and torque around 180 to 230 seems to be a good start. When all this is not good enough, time to alter weight distribution using ballast, most FF cars does very well with close to 60/40 distribution. Running more rear bias will make the rear a bit looser when braking hard into a corner, but better on exits too. I ran all the cars I tuned with stock weight distribution, some without weight changes like the Mazda video.
Hope this helps.
