OK, so I know that this question has been asked a 100 times before, but I'm asking it a bit different. For years I ran an NSX body but it has finally passed on. I ran it because I liked the look but also because it was low, had good balanced down force, and had less drag than some of the other bodies out there. Now I need to find a new body. I've read that the 350Z is popular at some tracks for the same reasons. Lately, I've seen a Mercedes AMG GT-3 coupe and liked its looks. I'm not that crazy about the Audi R-8 (personal choice and looks big and bubble like). Maybe I should start a different thread for this but I'll start by asking here:

McAllister Riley prototype with an HPI wing. Why? Don't know, must work well.

But the guy that wins every week does it with the Camaro body...

It runs in phases. There was a time when we had a field of eight 350Zs. But the Nissan is passe now.

I ran the Tamiya Subaru BRZ this weekend for the first and really enjoyed it. Granted, that day I didn't run it back to back with any other bodies to determine how it handled to a known performer, but I felt it was great. I was also running a Tamiya rear wing (see pics). One thing to note, though. The fender openings are HUGE.

Here's a pic of the stock body:


With the full ground effects and the body 5mm from the ground, the fender gap was still extremely unsightly and also caused the cg of the body to be very high. I trimmed it significantly to get an acceptable ride height. Notice the diameter of the fender openings relative to the tire diameter. Gigantic!


So I lost the entire front spoiler, but the car didn't push at all. I also didn't install the "winglets" at the rear of the front and rear fenders since I figured they'd get knocked off in a race.

The car also got lots of compliments yesterday. Maybe it looked good or maybe it's because it simply wasn't yet another HPI body.

I wonder if that huge fender opening is because that body is IFS friendly, and likes to be mounted LOW

I've been wanting to get one to run on my TA05V2, with the IFS front-end - but just haven't gotten around to buying one yet

Not familiar with that front end, but the hood is pretty close to the shock tower on my Xray T4, which also has independent front suspension.

its their in-board from suspension system - no shock towers, pushrods and F1-style things like that

I was just kidding. I knew of their system, but didn't know much about it. Regardless, my upright towers clear this body (even cut down like I did) quite well.

McAllister Riley and Corvette prototypes are popular at our track. They work well, but most guys run them because they like the appearance.

Yes on the end bell. We run blinky 0 timing esc's.

Congrats Tommy. Great run.

Running on a HUGE outdoor track, I liked the NSX, but found that hpi Mitzu Eclipse handled just as well.

Thanks! I know the Trinity guys were saying that the sweet spot in the D4 was between 52 and 58 degrees, but I believe they were using the Motorlyser to set timing. The Motorlyser reads slightly less timing than the end bell timing on the Trinity based motors (ION5 is D4 based).
