Front splitters on FWD cars tend be designed to aid turn in traction in medium to fast corners.

Couple of the racers over on Clubgti have had some success running plywood splitters and have reported much better front end grip in the twisties.

Its a replica wide body kit for the mk4 of the "mk5 gti w12" by Dietrich and its called WIZ or something, love the front of it but I hate the back, but I do prefer this w12 replica on the mk4 over the mk5  :lipsrsealed:

Thanks nick, any chance of some links as if it helps round the bends it still seems like a good idea, they running flat front undertrays as well?

Oh and whoever said rear downforce isn't needed on a FWD car is wrong, you do need it to keep the car settled in medium and fast corners. Hence why the FWD BTCC cars etc run quite large wings.

A wider wheel span would give a lower centre of gravity and obviously the thicker the tyres the better the traction in the corners BUT i wouldnt want the tyres too wide, they would just create drag on the straights and not give enough gain on the corners to compromise, also think about the cost of wide alloys and the tyres  :shocked:

as for an aero pack for the car, the slots in the rear arches can also be in the front bumper and front arches which would give better frontal downforce, i would but the slots in if possible, a front splitter and a rear spoiler to push the back end down, i wouldnt put the slots in the back arches as it would create more drag than downforce where a spoiler would do the job better.

r888's and 10j wheels will make my car handle fantastically!

The toyo tyres are used through out the whole time attack series! And they run on 12J wheels!

So to be honest the wider the wheel base the better!

Thought wider wheels had nothing to do with grip, I remember reading autospeed that tire width had nothing to do with the grip coefficient. The material/compound is what dictates the grip coefficient, wider wheels just allow the heat to disperse properly from what I remember reading. Anyone care to dwell on this?

the bigger the wheel, the bigger the tyre needed.

The more surface area of tyre on the floor = more grip?
