Good bumper for Aero?

[SandeepM3]

What kind of car is this for? Track, Street, Heavy dual duty?

If you have a wider track due to spacers and want a bumper to fit that, that doesn't look funny, its kind of impossible. It has to meet body panels that were designed for a smaller track width. If its a track car, then you take the funny/odd/over the top look for priorities. If its a street car, then dont bother, it will make such an insignificant difference.

You could try the carbon GT4 splitter that all the Nurburgring regulars put on their Ringtool M3s. It's rare to see Nurburgring M3s utilizing canards, most of them strap on this splitter and call it a day.

I'm going to create it in some software and test it out if I can. It doesn't do the job fully but I really like where I think the vorticies will come off of that one. It's a compromise between looks and function.

Someone did mention just putting blocking plates in. I found some free software the may be able to test the CFD. I don't track it currently but I will use aero on rallies. There's a Porsche ralley my dad and I are going to next year at the tail of the dragon. I'm going to need some good setting up for that. Sometimes I rip it in Mexico when no one's around also... and better aero equals more safety. Looking at all the Le Mans GT1 cars, they block the front tire yet you make a valid point about the body. It won't be perfect but there's a lot of room to improve.
