Fitting a splitter. What angle? How far should it protrude?

[MPETT]

I'm fitting a splitter to my Tuscan. Does anyone know technically how far it should protrude forwards and what the angle of attack should be. I've assumed it needs to protrude minimaly and the further forward it protrudes the more likely it'll get damaged by curbs and the forces acting on it. But I think it looks ace when you see more of it.



P.s. Has anyone else found 4 brass threads along the bottom edge of their tuscan? I'm assuming it's for the splitter and was fitted to non S models by default?

I've made a aluminium support that runs behind the lower lip of the "mouth" and that has 3 bolts going through it, through the fibreglass and into the splitter where I've used massive penny washers to spread the load. So I'll use this rear threaded mounts and hopefully it'll be secure enough, even in I use the position shown in the bottom picture.

Thanks for the advice. I'm not sure I have that much control to be able to mount it with a couple of mm of acuracy. Surly my fat arse getting into the car would upset that setting;). I'll go for a very slight downwards angle and see how that feels. Cheers, martin

That's a massive splitter you've made there! How much difference does that make? Do you race in the standard Tvr series or in a gt3 open category/class?

Hi Martin
Did you fit the splitter? How far forward did you decide on setting it?

I fitted it so that the Middle protruded about 3.5". My "mouth" section is custom so don't use it as a guide for a standard grill. I definitely feel a difference now. The rear feels a bit light, so may have to look at an "S" spoiler!

Any pics

Mines close to 130mm from the road surface, so could be an issue with curb stones! Here's the pic of the final position. I set it to as close to level as possible.
