Now for DCJs, Roche seems to be what most people get, but how do Spec-R compare (they have version 2 and P8, not sure the difference)? What about the ones that 3-racing makes? Most will work with the kit spool outdrives?

Thanks!

fyi
c-hubs are not the same as BD5
"B7" reference are BD7 parts

Ran the excellence lab chassis last night during club race on carpet. I arrived at the track really late and missed a qualifier, so tuning time was very limited. Overall impressed by the fit and finish although bit pricey compared to the factory aluminum.
I'm not the top racer at my track, to run a fast race lap/time I always had to be near perfect to achieve this with my other 15 with aluminum chassis. Overall I was able to shave approx 5 seconds off total race time on this 15 with a slower motor. Next outing I will swap to a faster motor and see what it can do.
I'm not very technical at explaining things so bear with me. If I were to compare this chassis stiffness based off driving feel it would be in between the factory carbon and factory aluminum.

Good luck with the 4.2 arm mount. You can get them in blue from almost anywhere, but the black ones are impossible to find right now.

Aluminum chassis is available from any of the asian retailers. I recently ordered one from Banzai, but I think rcmarket also has them in stock.

B7-00214
B7-00314
B7-32L (or B7-32LB)
B7-32S (or B7-32SB)
B7-644T14
B7-674B
B7-630B

I wouldn't worry about changing the steering the 13 steering fits fine and geometry didn't change. You do need to use the new pulleys they have a better fit for the smaller bearings.

I think that's it.

Beth.

I should also add I am convinced the 15 motor mount B7-32L15 should fit the 14 chassis, It is a stronger mount. I just havnt had time to test to see and swap it between my 2 cars.

Does anyone know the difference between the two kinds of Yokomo belts available? For instance the YOK-BD-516L and YOK-BD-516LB? The L belts are black on the toothed face while the LB ones are tan/brown.



The pictures are front and rear belts but I'm referring to the difference in the toothed face.

BD7 Parts List

Low Friction Belt

Ideal for stock class of touring car, it is low friction rear drive belt for BD5 / 7. Use a flexible material than conventional, to prevent the drive loss.

The low friction belts are very good but even in 13.5 dont last very long.
And without warning they go all puffy.

Those of you with a Hudy setup bench... can you please drop your car on the setup station and check whether you have symmetrical rear toe? Mine sure isn't... I've tried wiggling all the three a-arm blocks, as well as replacing the RR block by a 2.5deg one, my right wheel is still 1deg off...
