B4+8mm indoor setup
 

Hello

I need a good carpet setup for my b4 +8mm not b4.1

I have b4.1 rear tower and b4.1 inboard toe-in adjustment.
all b4 factory team carbon exept b44 rear arms and hubs

Setup:
30 deg caster blocks
axle height located in middle pos
Brown front spring no2 piston 35w oil
Green rear spring no1 piston 25w oil
Front link setting 1 a no washers -1deg camber
Rear link 1 b no washers -1deg camber
0 deg antisquat
Medium wheelbase
Shock pos rear: no1 (inner) tower inner on arm
Shock pos front: 2 middle on tower inner on arm

Lipo forward pos.
Rear ballast weight (28g in front of gearbox)
7g in rear pockets
10g on servo

Im looking to get better steering, rear end feels good.
I need moore low and high speed steering.

One more ting: diff setting, i have always set my diff as loose as possible (without diff sliping), manual says thight to bottom and loosen 1/8 is the manual setting preferable from the way i use to set my diff?

Thanks

My B4.1 WE Indoor setup:

Front
35wt oil
AE Silver or Blue front springs.
Piston 2
3 (or 2) limiters
top inner hole, bottom outer.
wishbones level ride height ~21mm
1/2 - 1 dec camber
30deg caster blocks.
0-1 deg toe in, adjust toe as you need. 1deg toe out works sometimes.
Top link ball studs: 1 and A, with two washers.
Brass front bulkhead, and as much weight in the front round servo as you can (I use 30g in 5g stick-ons, with low profile servo). The brass bulkhead is the key bit you are missing. It will really give you loads more front end.

Rear
30wt oil
AE Silver and/or Blue front springs.
Piston 2
1 limiter
top inner hole, bottom outer.
wishbones level ride height ~21mm
1/2 - 1 dec camber
0 deg antisquat.
2 or 3 deg toe block
Hole 1 on the U brace. I shaved it, but used 1 washer. I also use the carbon C hub tops. if using kit hub tops you don't need to shave the U.
Hole C on the hub top.
kit rear ballast weight
Fill rear triangles with stick-on weights, i got 15g in each
I also put about 15G on the receiver side to balance the esc on the other.

The key bit is the right tyres to suit your track. Speak to the local A finalists.

On the smaller/tighter indoor tracks, I found the car was better with the same setup as above, but with the shorter/older none + 8 chassis. you can normally pick them up ~£10 unused but second hand.
