B74 vs B74.1
 

Hi does anyone know what the difference is between these 2 buggies :confused:

I got my new to me B74 at Xmas and have upgraded the following parts. G10 chassis braces to reduce the stiffness of the chassis, the longer B74.1 rear driveshafts, LRC rear wishbone mounts, +3mm steering rack and B74.1 diff shims.
These were recommendations by RogerM, and bring the car pretty close to a 74.1. I have not changed shock towers or rear wishbones yet, I am waiting to see what is considered a good base setup when we can get going again!
Cheers

I think that the LRC C & D blocks made a big difference to my B74. I already got the RDRP +4 steering rack as I really did not like the amount of bump steer on the standard rack. I have got the RCMx LCG towers but made a mistake by not limiting the droop on the rear end meaning that the dogbone ended up coming out of the diff output. The newer axle and longer rear dogbone is really interesting as it moved the pivot point on the axle inline with the bearing so it is closer to the pivot point of the rear hub. I have some of these coming tomorrow :)

I have the same shock towers on my car, and noticed the 29mm stroke on the rear shocks left the driveshafts very close to the edges too. How much stroke have you now got? I think 28mm might be the max, might still be a bit too much.

The rear wishbones are the same part number as the b74. Are these the new ones?
I’ve put the lcg towers new shock bodies and shafts. Also the new steering rack. Think I’ll get the new c and d blocks
