Best way to increase downforce ??

[tech1889]

I do understand all them things.. i no what they are used for i was just curious thats all.. Just wondered why my car over like 115 the steering gets all wooley like its lifting just wondered a cure for this as over people have had the same problem..

Just look to the old 80s and 90s Fords for a few ideas. The gurney flap was used on the RS500s already massive rear wing to increase downforce. Also if you want to know what happens to cars when they take the downforce spoilers off...

That was not caused by a loss of downforce, from memory the gearbox seized.

before my time but talking to my dad he seems to thgink you are correct on the gearbox issue!

is your tracking ok?

Yer tracking is all good..

Never heard that the gearbox had seized, just that they had only removed the rear wing a few miles down the road. I've seen the footage of it going off the road from the car they were overtaking, thinking about it, could well be the gearbox, it just suddenly lurches right across the road...

I remember it from a feature in Fast Car, 99% sure the gearbox or transfer box seized, they are rebuilding it into another shell.

Get your camber checked out, -ve camber will make the steering light at high speeds.

To creat frontal downforce on a mk4 at a guess i would say an R32 bumper with Cupra R splitter would be your best bet, purely judging on the aerodynamic properties of the standard compaied to the R32 bumper. The R32 with larger vents would allow cleaner air flow, the standard bumper also moulds in towards the car at the bottom of the bumper which wouldnt exactly help unless a large front splitter was added which would stick out far to far for every day use(as mentioned). The cupra R splitter if mounted in the right place could help as it would work as a small front splitter, if mounted incorrectly it could create drag as you could be creating a pocket between the bumper and splitter? I would also fix the Bumper and splitter on as tight as possible, also smooth the bumper into the wings and try to seel up any gaps in the body panels.

If your wanting a higher top speed i would work on the untray of the car as there is not alot you will be able to do with the body aerodynamics. The mk4 isnt exactly going to cut through the air very well, in all honesty it was the aerodynamic properties of a 1 tonne brick lol

thats my thoughts on the matter 

good luck!

I seem to remember he was trying to over take someone and ran a little to wide off a foriegn country road and the rear wheels came into contact with a dusty, sandy sureface next to the road and he lost traction and control of the car. Happened in the gumball rally of europe
