B4 setup sheet for Seaham? Any tips for a 1:10 n00b greatly appreciated!

[kwik_uk]

Hi,

I've just bought a second hand B4 from a link on here.
It came as follows:
Speed passion ESC
13.5t Exceed motor
5000 lrp lipo
Big bores from the 4.1
Green springs on rear white on front
Unknown shock oil/pistons
Ali hubs on rear
Ali motor mount

I ran it straight out the box as I didn't get the chance to strip down before racing on Sunday.


Can you advise on a good set up for Seaham?

Advice I've had so far is Schumacher spikes in yellow all round.

I've looked at a few sheets from workshop but was wondering what you guys thought?



I felt like I had no grip on the smooth floor at all!

Any help would be very welcome

Cheers,
Mark

Hi Mark,

My B4 was really good at Seaham on the folowing setup:

Rear:
30wt oil
silver springs (I'll bring some for you)
Middle on shock tower
inside on wishbone
Short wheelbase
1 deg anti squat
Long upper link
Std toe in
-2 degreee camber

Front:
40wt oil
Blue springs (I'll bring some you can have)
Middle shock tower
Outer wishbone
-1 camber
std caster
0 deg toe inn
trailing steering blocks (std)

30 grams on top of servo, and a correctly adjusted slipper clutch.

It felt reasonably safe and fast like that. Change to silver spring, 35 wt in front if you need more front end.

Rideheight ... wishbones just below level.

It came with some weights in the box. I'll take a look when I get home and see what they were

Cheers

Ah Chris that's fantastic mate! Thanks very much!

I'll get the car setup (other than the springs) ready for the meet on Sunday. Can't wait to try it out with a good setup and some sticky tyres!

Hopefully the bits I've ordered will make it through the snow!

Also....

2 mm under front ballstud on front shock tower, 1mm on rear inner ballstud if on B4 rear brace, 0mm if on B4.1 rear brace as it has the little raised section on it.

Chris,
Just a gotcha on the springs you are going to bring, Mark has Big Bores from a B4.1, currently fitted with Green rear and white front.

Based on spring rates that is 2.00 and 3.30, compared with 2.10 and 4.20 for the standard silver/blue setup. Am I right in saying that you can afford to run higher rate on big bores, because they are more progressive?

Looking at that he may want harder front springs to balance with the rear rear grip he has?

[chrispattinson]

Good point Ian, all of my spring references are for small bore shocks, therefore I don't have springs for you to have Mark. Sorry.
Ian is correct, you need some harder front big bore springs, rated , if possible , slightly harder than 4.
