Default Notice anything different on these RC8bs?

These pics were taken at BRCA Nationals Round 3. No risers and new shock towers:

Looks like an update for the RC8b is coming up! Its about time they got rid of the risers.

They raise the CG of the car a lot. No other 1/8 Buggies use risers. Not using risers will lower the shocks about 1/2 inch.

They are home made parts from Mick Cragg for Neil to try (been on the car for 2 races now). Nothing factory about them (hacksaw and dremel job)! I know that because i pit with these guys at races. They are just trying things out like any other team. There is no planned release for a new car, simple as that. You wouldn't believe how hard the UK AE team work at trying new things out on the car (mainly shock internals) to try and make it better for the team and other non-supported racers. Look at Robert Battles car, he has non-factory blue towers.... does that meen a new car is to be released(he's had them on since before Neo)? No. I don't personally see what's wrong with the shock risers anyway???? Don't stir anything up unless you know what is actually going on...

LOL, relax I'm not trying to stir things up.

In my mind this setup is much better than the riser setup. On the original RC8 the shock were laid down at a radical angle and the risers needed to be there to give the shocks clearance of the bulkheads. With the new RC8b tower geometry you could get rid of the risers. The risers increase CG dramatically. No other car uses them. If they don't need to be there, they can get rid of the risers. I could see AE doing this on a future version of the RC8. I don't know why they wouldn't.

You're right, just because some of the drivers have non-factory stuff on their car doesn't mean it will be upgraded to production cars. But if a modification works well for all the other team drivers I can see AE implementing some changes.

the risers are fine. if they were that bad Maifield and Cav wouldnt been winning races like they do... and if associated thought and heard that they were that bad for the car they probably wouldnt have put them on the B when they released it.. just my opinion.

Just because something isn't "bad" doesn't mean it can't be improved. Honestly winning races has nothing to do with it. It is about making an improvement to the vehicle.

Risers aren't the best. They raise the CG of the vehicle significantly. With the same length of shock and a shorter shock tower the CG of the buggy would be greatly reduced.

If 3 of their top drivers are running this setup, I would bet there will be a factory change made eventually. This is always how improvements are made. It is the team's job to test new things in order to improve the vehicle. If this setup is good enough that 3 of the top guys are running it, you better bet it will eventually end up on the production car.

How much does it lower the CG? How much does running a body wrap raise the CG?

Not sure. Couldn't answer either of those questions. But risers certainly do raise the CG. Hold all four shocks in one hand and tell me lowering them by about 1/2 inch won't lower enough weight(CG) to make a difference. I don't think people realize how much a set of big bore shocks actually weigh. The lower the weight is mounted the better the vehicle will handle. That's simple physics.

..just measure from the hole in the riser to the hole in the a-arm, and that will tell you how many millimetres.

LOL, its about 1/2 inch lower. A body wrap doesn't matter because it weighs next to nothing.

Like JAMMINKRAZY said, the big bores weigh a lot. Every other 1/8 buggy doesn't run risers. There is a reason. Lowering the CG on any racing car is a priority.

I should start making mine! I just need some dimensions and carbon fiber...

..that's a significant amount indeed and would certainly be felt on the track. It looks like he doesn't run boots on his shocks either, wonder why??
