Performance

Yes, there are faster cars out there but this car really is shockingly good.  On the current 22psi tune It posted up dyno numbers of 404.51 AWHP, 457.11 Torque.  It was on stock intercoolers and did not have water/methanol injection at the time, but did have 3” AR Design downpipes.  On the track we placed first in almost every TTS race we were in and this is a very fast class.  We even set two track records at the time, and one was on a weaker 18psi tune (379/429) and a weaker brake setup.  We had issues with keeping the engine cool on track with the 22psi tune, but not the 18psi tune.  No problems on the street.  It weighed 3403 with stock front seats, larger custom radiator, a huge oil cooler, and stock hood, but no spare or back seats.  I suspect that the seats and hood dropped at least another 100lbs from the car, stock seats are heavy.

What Does it Need?

The issues are mostly cosmetic with the car.  There are little nicks and chips on the car, especially the door edges.  The front bumper is in especially bad shape from rocks and going on/off a lot.  It was connected using quick release dzeus fasteners and one is broken so now a bolt is holding it on which is the standard way of attaching it.  I never screwed down the door sills and the front doors have rubbed the paint off.  I was trying to come up with an elegant way of attaching them and so they need paint.  The CF hood has a crack in the middle, about the size of a baseball.  I was planning to repair it and paint it but haven't.  The informational screen is burned out on the dash (common) as well.  I noticed a slight vibration when the wheels on the back where on the front, and those might need to be straightened.  One of the front wheels has curb rash.  The driver’s side 02 sensor at one time came loose and melted from touching the turbo.  It is currently hard wired and has been for a long time with no issues.  It will come with the original seats but the driver’s side has a small tear in the bolster.  Mechanically everything is up to date and runs great.  

On the Widebody

The most distinctive thing about this car is obviously the RS4 widebody.  I used factory front fenders, bumper, sills, rear door, and grafted in the RS4 rear 1/4 panels.  The work was done 4 years ago and has held up great to thousands of miles.  No evidence of the seam line at all.  The backside of the rear 1/4 panels was sprayed with a sealing wax to fight rust and corrosion.  The rear bumper is a stock bumper that was modified to achieve the look I was after.  Smooth sides that are flush with the body work and flowing tail light covers that are integrated.  The lower valance is also bonded together to give everything a much smoother look.  The paint color is from a BMW motorcycle and is called "Mandarin Yellow".  I'm often asked if the color is yellow or orange to which I answer, "Yes."  Depending on the lighting it can swing either way and is very eye catching.  The original color was Imola Yellow and that color can still be seen in the engine bay and a small area of the trunk.  The car currently sits on 265/35-18 all-season tires but raced on 275/35-18 Nitto NT-01 tires.  This required a 5mm spacer in the rear.  I've run as large as 295/30-18's on the car, but it would rub under full compression and was probably too large.  The front bumper has been mostly shelled out for weight and does not have working headlight sprayers.  I believe I have all of the parts if someone wanted to install them, but I didn't intend to drive it in the snow or mud any more.  While on the subject of bodywork, the rear bumper is off an early A4 for that European look.  Also I want to point out that it has no sunroof but a carbon fiber plug to fill the hole.  This was done to save weight and the original headliner was recovered to block the hole on the inside.  It would be nice to get a non-sunroof headliner if a person was so inclined.  Some of the pictures show the old TDR 1.2 wheels in 18x9+15 that are black.  I know that is confusing but I wanted to include those pictures for reference.

Photos and Video

Here is a gallery of the car from over the years.

General Photos

I tried to put together a detailed photo gallery, focusing on the worst areas to minimize surprises for any potential buyer.  When you focus on the bad it tends to make you think the car looks really ratty, but that is not the case in person.  If there is additional pictures you would like to see please let me know and I'll take them for you and put them in this directory.

For fun, here are some promotional videos made by AR Design featuring my car.  I no longer have the downpipes on my car so it isn't as loud, but you get to see the car moving and it’s entertaining.

Here is some video of a track day with the car.  This was on it's slower 18psi tune and not on the race pads and rotors we added later.

Mechanically the car needs nothing that I know of, runs and drives fantastic.  I just took the car and passed Colorado emissions and will include that certificate with sale.  Also of note, the secondary 02 sensors have been coded out so it won't throw a CEL if you run without cats on the track.  Also the EGT sensors are coded out but they did work fine at the time we tuned it.  There is a airbag warning light due to the race seats but I have sourced the correct resistors to stick into the plug to make this go away and will include them in the sale.

Final Thoughts

The car is fantastic to own and while it needs many small things it does perform and look great.  Some people had expressed concern that the car was abused on the track, but it only saw 5 events the one year and we only ran the car for about 10 minutes to put down a fast time and then parked it.  The price of bodywork and installation alone is worth the asking price.  People are always looking at the car, driving though the parking lot to check it out, taking pictures of it.  I loaned it to a friend and in the two days he drove it he found two different notes left on it.  When you hammer it getting onto the highway you giggle every time.  It’s a wildly entertaining ride.
