Custom made front splitter

Hi guys I'm making a custom front air dam splitter, I'm using aluminum, i think it's going to be 3 inches away from the front bumper. So i want to know if there's going to be a lot of downforce on the front when i'm going fast. The fastest i go is around 130mph on the street, and i am not thinking of buying a rear wing.
Can the car lose control at high speeds?

130mph on the street is not very fast. With enough aero and delimiter programming, you should be able to break 140 brah.

Yes it can lose control but only if you don't have enough downforce preventing you from lifting off. Hence I highly suggest getting a big wing on the rear.

I know I can go faster bro. but how fast can I go without a wing? before losing control :s

I been 160-165 I'm streets with no wing or splitter on my z4mr feels very stable. But i guess putting down force in the front and not in the back can change that.

Yeah, but he's got a coupe. The added natural aero is good for more rear downforce and about 10-15 mph max over the roadster anyway...

I second the vote for a wing...

...A MASSIVE wing.

I'm thinking APR GTC-500. 70 inches of pure Keep-You-On-The-Road. Probably the only true safe bet.

Do you think a roadster will look good with the massive wing like the APR they put on the coupe. I actually have never seem one yet in a Roadster. You are most likely right.

You'll be fine at 130mph. I don't use a splitter but the car (at least the coupe) feels very stable at 158mph (somewhere in Mexico on a closed course) so I doubt a splitter would make your car unstable at only 130mph.
