My Ride: HPF M3
Modified Skidplates? Aftermarket Under Brace?

My HPF car doesn't have a skidplate, which is a no-no in my book. Comparing how the car feels in turns compared to my NA M3's with the plate, it feels mushy and sort of "loose". I know HPF sold a underbrace at one point in time but even that doesn't utilize all of the stock mounting holes. What kind of solutions do you turbo charged folks run? or do you just go skidplate'less? :O

I have a fabricator who is making a trunk brace for me, i'll ask him what he'll charge to fabricate a under brace similar to the HPF one and or if modifying the stock skidplate is possible.

I'm just running a modified stock plate with the Max PSI kit, as per their instructions. It has about a 4x9" cutout and doesn't lose any of the mounting points but a bit of strength in the right control arm mount

I don't have my own, but I found one from Maximum Psi's release thread. They removed a little more than I did but you get the idea.

Sweet, thanks. I'll look into doing this, should be similar with the HPF piping.

Modified Skidplates? Aftermarket Under Brace?

I found this.... Thought it was interesting. Might be worth looking at? Reminds me of a snowmobile

I have HPF under brace and have plans for reenforcement tying in two of the mounts that the factory uses.

Interesting, seems like a plate to protect the lower charge pipe.

yea, I think this paired with the "modified" OEM underbrace (like the one shown in the max psi picture) would be the best/cheapest option

My Ride: E46 M3 Turbo
I always thought running the intercooler piping under the car like these US companies did was so lazy.



This was the underneath of mine when it was turboed. Still stock looking except for the oil and water lines for the turbo you can see through the underbrace. And I had a steering column there to deal with as well. And I made this all work on car stands in my shed. You would think a company selling this stuff would get it right.

This pic was looking through from the wheel well.

Thanks for posting 02pruv maybe this will make some of the companies think about a better option.
