Anyway, I'm trying to settle on what engine to run in this thing. I have a new Jammin JPX 21, and a new Losi 454 with closed backplate.. Not sure on either. Would really like the Alpha 23. Kind of assume a 25 - or something between a 21 and a 28 would be ideal.. What do you guys run? Not gonna be racing, but will be running on onroad tracks primarily.., and not splashing out for an OS 25 - which I would imagine is the dream engine for this car...

Kind of worried the Jammin will lack the balls down low, and I'm not too keen on the Losi cuz it'll drink so much fuel.. The Losi though I expect to have good power for it...
What did you do use the stock SC8 suspension? I have a SC8 that I will try to convert. I have tried a few motors with great results. All are .21, I use my car only for racing. I have used:

Novarossi +35 - Awsome race engine great top end nad good bottom end
OS VSPEC (old blue head) - great all around power but it lacked a little top end
OS Speed - Great engine power all around with more top end than regular VSPEC
Reedy - good bottom end not too much up high. Good offroad motor not for onroad
RB Murnan Modified - This motor is a beast awsome down low and revsto the moon. I got this motor from a friend that loaned it to me since I needed a motor (I had no back up at the track). It was soo good that I ended up buying it from him

Just the wheels are SC8. The suspension was not set up right.. I had a bunch of pre-load set to up the ride-height a bit, cuz I knew I'd be in a rough parking lot...

Anyway, I think the bounciness was mostly just down to the big SC8 tires...

Back to engines, if a decent 21 is powerful enough to throw it around, then a Jammin 21 should be good, right(about as powerful a stock 21 as you can get from what I have seen..)? Don't necessarily want to drift all day and smoke tire sets gratuitously - but I want it to be ballsy....

Random question: I took off the side-bar things, but after seeing how d.amn fast the car is, and how quickly it can go spinning, is it maybe a good idea to put them back on, as they would afford some kind of protection on the sides in the event of a crash into a curb or pole or whatever? Kinda' seems like it...

I kept the side braces on my DM1, the body stays in place and you have some protection against side collisions from another car. Curb and poles are costly accidents, so you definitely need to drive with sticky tires and some restraint on the throttle

The Spec does not come with them. Does anyone know if you can add them easily? I've converted mine to brushless, so I have my doubts.

I would keep the side bumpers on, remember that your servos are exposed without them. Having your throttle servo unprotected isn't a wise decision, one good hit to that servo and you'll have one hell of a runaway. If I remember correctly you had some servo linkage problems or missing parts when you bought the car, no need to go through that again. Friends of mine that run the Spec have no choice but to run without the side bumpers. Ofna supplied that kit with the side bumpers, but the connecting rail is to long for the chassis.

I purchased my DM1 Spec new (2008) and the side brace parts were included in the parts bags,
but there is not enough room on this shorter chassis to mount the brackets.
At least I could not find the room.

Hmmmm if I'm not mistaken you can mount the posts to the chassis, but not the connecting rail.

Hmm.. I guess they figured that out. Mine was purchased in September of last year and did not come with them.

Thanks for the info!

Yeah no problem. But even if you get the side bumper kit, you'll still need to make the connecting rail. You could make it out of 1/4" plastic easy enough.

I know none of that coming from a basher who jumps his Savage off his roof, but I am learning. I'll keep those in mind.

As long as your not jumping your spec off of the roof, your doing alright!
