Default recommended hop-ups for a TC4?

Okay, I'm not quite a rookie but in touring car I might as well be....thanks in advance to anyone who has advice on the following:

I'm getting back into electric touring after several years "off" from racing. I used to have a TC3 and I ran stock on an indoor carpet track that was mostly tight and technical. Now I will be racing outdoors on a massively large asphalt track which accomodates 1/8 scale nitro cars. Also, I plan to run a much faster motor (a Novak Velociti 4.5) than before. I've settled on a TC4 as my new car because AE is what other folks are running there (so I can get advice) and because AE parts are easy to get from both nearby LHS's.

Figuring I will be dancing with mister wallboard somewhat routinely as I get back into things, I think the "Team" (not "Factory Team") version of the TC4 would be smarter for me because I'll just snap and bend a bunch of nice fancy aluminum and fiber stuff learning the ropes again and getting used to faster speeds. However, I would like to beef the car up a little from its stock configuration and would like to do so during the initial build to save time.

So, along with ordering myself a TC4, what sorts of initial add-ons would folks recommend for someone doing long track ashpalt racing? My initial thoughts are at least the steel outdrives and some roll bars. Would a one-way in the front be a good idea? What else?

I also just built my first car, a Team TC4, and I'm a novice and raced it in my first novice race, aka demolition derby, and it survived perfectly! They were using roadrails so I was flying and flipping and crashing all over a dozen times.

I would highly recommend replacing the bumper with the TC3 wide one. Not a single crack in my front body and protects the a-arms.

- Parma ultimate bumper wider front bumper.
- Team Associated VCS2 (bladder) shock caps.
- Whip Racing Innovations carbon fiber driveshaft (more).
- IRS aluminum (w/pin cushions) or lightened steel outdrives.
- Aluminum TC3/TC4 screw kit to drop weight.
- FT aluminum servo mounts.

Thanks, that sounds like a really good idea (I had a huge wide bumper and nerf wings on my old TC3 back when I was stock racing). Do I need all four of those parts to put it together? Does one of those pieces go on top of the foam block to lock it down to the bottom part? Thanks for your advice!

Cool ideas - I'm a little worried about the shaft though, that page says it's "not recommended for use with low turn modified motors" and the Velociti 4.5 is pretty beastly, it's the brushless equivalent of a "low turn" modified motor. The outdrives are an excellent idea, I've read a lot of people destroy the plastic ones. Is there a reason to prefer IRS aluminum or lightened steel to the AE lightened steel ones? Thanks for any additional information, I appreciate the help!

I think the driveshaft would hold up ok on asphalt. You'd have to ask but I believe they based that concern running a low turn mod on carpet. Depending on the traction of the asphalt the driveshaft should see less torsional stress. I'd be concerned with the team TC4 not having a top brace and in a hard head on crash chassis flex could allow the input drives compress the driveshaft bending it to a point it breaks. I've been running my FT TC4 on carpet weekly the last 5-6 months with the driveshaft in 19T and mod. I plan on running my team TC4 on asphalt with a mod equivalent brushless this summer so I'm going to find out how well this combination holds up.

I prefer aluminum outdrives for a little less rotating mass but it's a must to replace the pins in the dogbones with IRS pin cushions to prevent outdrive wear. The lighten steel outdrives are slightly heavier but hold up just as well.

Thanks again. Hey FWIW, I have seen photos of people fitting the upper brace from the FT kit onto the Team Car, so it can be done. Not sure if it requires a little work, but I'm guessing it's probably not too hard...
