I must say, I just finished building the kit, little disappointed, I thought I was paying double the price of some kits because the rb6 was akin to a AE factory team having all aluminum hop ups, the shocks are nice but no aluminum rear hubs? No aluminum washers? Don't get me wrong it's nice but it better give me 3 seconds on the track for this price

The car is awesome and doesn't slop out like the AE cars. Good luck. Three seconds off the bat is alot to ask for but with patience and some tuning it may be the best car you have ever driven. In my opinion the car has superior diff, shocks, plastics, etc over any other car especially the AE cars.

I'm not necessarily complaining and was joking about 3 seconds, and yes I read a lot before deciding, I was just expecting a tiny bit more for the price. Diff, shocks and plastics are definitely superior.

Do must recommend running saddle or shorty? If shorty, do you prefer esc front or back of shorty

I hear you'll get best results esc behind servo with saddles. Haven't tried it yet myself.

No changes are made to make the rear bulkhead any stronger. The revision adds holes to mount the new brass weight kit and also includes mounting brackets for the rear sway bar kit.

actually the ball stud holes are a little deeper on the new piece. This should actually help out with the issue you had. It's also not a bad idea to put a grub screw in the hole that you aren't using. It reinforces the hole you are using and makes ripping out the ball stud even less likely.

I found the grub screws in the other holes is actually worst, the ballstud breaks instead of flexing in the hole. The plastics are real tough and I haven't been able to pull out a ballstud (ballcup pops first).

Good afternoon Gents,
for the rb6 mid mount, if you look from the side view at the rear shocks, do they lean at an angle coming down to the eyelet when you mount it on the rear arms?, meaning it is not perpendicular down straight. i have now used 3mm spacer just to just it almost straight down, will there be any adverse effect on the handling or should i just leave it ?

any comments?
