Dunno. I'll leave that to Mark and the G4 crew to give a definitive yea/nay. Since you have a 2nd Gen, Ladayvalea, you are probably safe. The 1st Gen cars, where the mufflers are at the corners, are going to be the bigger issue, since most of them hang low enough to interfere with the diffuser design, I believe.

 

And if I were to read ALL of the new messages, not just th eone comin immediately after my own... /facepalm

 

bit out of the blue, but i have an r50 with an offset rear exhaust, what are your thoughts on having the just the front splitter in terms of affecting the balance of the car?

i will eventually being modifying my existing exhaust's exit point but that is fairly far down on the list, and with my paltry hp i don't much fancy a big wing adding drag as well as downforce so would prefer the diffuser over the wing for rear grip

basically how heavily do they depend on each other to balance the car? also do you end up with enough downforce to require stiffer springs?

 

DAVE

Let me know how it works. I'm not going to do a straight exhaust. I'm loud now. :eek6:

 

I'm going to be honest with you, adding the splitter is going to make the rear end easier to let go, even more so then it is now. If you don't want a wing you could add a spoiler with our extender on it and the balance would even out. The right wing would be adjustable for the street and different tracks. You can adjust it for the street with very little drag and still achieve down force for stability. We are testing different versions right now.
I'm not trying to talk you out of buying our splitter because it is adjustable and easily removed.
No you will not need stiffer springs unless you end up going over 100 mph through the corners.
Call me if you want to.

:crazy: I'm going to try and answer everyone right here right now. If I miss someone holla at me:

Ladyvalea do not worry about the exhaust connnfusssion, you are O.K.

UKCoopeR & phudeaux you are correct , the stock and some aftermarket exhaust ON R53s do interfere with the diffuser and it's purpose :cornut:, they also suck a lot of HP with all the bends and small diameter pipe :eek6:

ninimark I am going to use my '03 S to give you a straight answer. Hang in there with me for a day or two :idea:

cct1 you will get all hardware including newly designed support plates I've been wanting to talk with you but can't find your number ut:

Newbs49 we can build you a quiet straight exhaust, Leon has one for his as of now. There's Steve's, loud, there's mine, in the middle, and there is the quiet one Leon and Wayne have

How am I doing......OH YEA---Dave:lol:, just kidding, saving the best for last. My e-mail is my account [email protected] :devil:

Don't want to say no, but there's no quiet in my car with Jan's toys and long tube racing header. You can even ask him. Plus I don't want to lose any of the 249 HP.

Thanks for the offer!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Mark--email sent.

One other thing--I'll throw it out here on the boards--are underpanels still on the drawing board?

 

Yes-sir-rooney the belly pans are on the drawing as are 7 different wings and "DFG" designs, side skirts and some secret stuff :devil:

Newbs49 youwill not lose any of your HP, you'll gain by getting rid of the bends. Talk with Jan at RMW about it. Just thinking out loud
