A trait of the track is that it appears to have quite low forward traction, so when putting on the power, the rear end tends to wander and step out. To counter that I have got the car to be pretty good in the tight stuff, but not so great on the initial turn in particularly.

Has anyone got any particular suggestions that I could try? I still have to write my setup down, but basically I have:

F R
Oil: 40/40
Piston: 3/3
Springs: Yellow/Yellow
Sway Bars: None
Camber: 1/1
Caster: 4deg
Front Drive: Oneway
Center Drive: Oneway
1mm Antisquat
2deg rear toe
0deg front toe
Shock Angle: medium angle on front/fairly upright on the rear
Motor: DC Motorsports Modified
Droop: 5mm front/2mm rear
Tyres: CS27
Body: Mazda 6
having a look at this setup what lower arm mounts are you using how many washers have you got under the inner top link and what wheel spacers. also i see you have got the same shock oil piston and spring front and rear in my experiance this tends to make the car little unstable espically off power and mid corner the car tends to hook mid corner what you could try i use when running mod is.

FRONT
oil AE 40wt
17.5LB spring
3 hole piston
3rd hole shock tower (from outside)
middle hole lower arm
4deg caster
2deg camber
2.5mm spacer under top link inner. med length
1A front and rear of lower arm
3mm spacer behind lower arm wheelbase
front role bar yellow

REAR
oil AE 35wt
15lb springs
3 hole piston
2nd hole shock tower (from outside)
middle hole lower arm
3deg toe in
2deg camber
0.5mm spacer under top link. long length
1xb front of arm
1c rear of arm
1deg outbourd toe in
3mm spacer in front of lower arms wheelbase

mazda 6 or rayspeed accord
centre one way + front one way
cs 22/rp24 pre glu

droop i use is set by how much spring movement between coller and retainer on the front just touching both coller and retainer (no tension tho) rear droop measred 1mm from coller to spring.

used on high grip bumpy uk circuit pretty much the same on smooth circuit apart from pistons to 2 holes front and back also fixed spool and centre pully if grip is low.

give it a go

How about a rear sway bar for more high speed steering?

Hey Guys,

Thanks for your thoughts on what my problems may be. I made a few errors (droop mainly) when I wrote up that rough guide of my setup and now I will post what I exactly have at the moment, but hearing the thoughts on antisquat from Eirik, it makes a lot of sense.

Anyway, this is my setup as per Ed Clark's slightly Modified Setup Sheet:

Front:

Upper Arm Position: 2
Upper Arm Spacer: 2mm
Upper Damper Position: 3
Lower Damper Position: 3
Susp Mount Spacer: Front-0, Rear-3 (block flipped so equates to 0)
Caster Block: 4deg
Camber Angle: 1.5deg
Ride Height: 6.5 (Track has some big bumps in it)
Droop: 2mm (measured on Tamiya droop guage with shocks/bars all disconnected with suspension free)
Front Drive: Oneway
Roll Bar: None
Wheel Hex: 5mm

Rear:

Upper Arm Position: 2
Upper Arm Spacer: 1mm
Upper Damper Position: 4
Lower Damper Position: 3
Rear Upright Position: C
Rear Upright Upper Spacer: 1mm
Rear Hub: LW 0deg
Susp Mount Spacer: Front-1, Rear-0
Camber Angle: 1.5deg
Ride Height: 6.5 (Track has some big bumps in it)
Droop: 4mm (measured on Tamiya droop guage with shocks/bars all disconnected with suspension free)
Centre Drive: Oneway
Roll Bar: None
Wheel Hex: 5mm

Shocks: In this case, same for Front and Rear

Foam Bushing: None
Piston: 3 Hole
Shock Oil: Schumacher 40wt
Spring: Tamiya Yellow

Front Toe: 0mm
Front Suspension Mounts: Front-A, Rear-XC
Rear Suspension Mounts: Front-XB, Rear-B
Bumper: Square Narrow Bumper (ala Rheinard, Maezumi, etc)
Lower Deck: 2.5mm
Front Susp Arm Spacer: Front-1.5mm, Rear-3mm
Rear Susp Arm Spacer: Front-1.5mm, Rear-3mm

Motor: DC Motorsports 9x1 Modified
Spur: 102 Pinion: 26
Battery: Harris R/C or DC Motorsports IB3800
Body: PF Mazda 6 with Std Wing
Tire: CS27W (Control Tyre with TO Medium Insert)

Okay, I think that just about covers it. Sorry it takes up such a huge part of the page, but I think that most of us benefit from learning about setup change with a setup to tackle. I like the ideas that some have come up with, but with every detail covered now, I hope that it can help even more to sort out the cars problem of mainly lack of front grip, particularly at high speed and corner entry. On power, the car turns very well.

I would test these :

Front:
Caster Block: 2 deg ( more vertical ).
Ride Height: 6.0

And tighten little bit ( 1 or 2 hour ) rear ball diff.

Pro Dive ( front susp. hinge pin tilted downward ) if anything fails.

I'm looking for a breakdown on the differences between the different suspension mounts (i.e. A, B, C, D, XA, XB, XC, XD). I know the X series are narrower but that's about it. I found a post here that there was a instruction sheet in the worlds kit that included this but that doesn't really help me. Any help would be appreciated.
