What effect will these have on TLR 22 steering?

[michael77]

I am trying to get into buggies and racing. I have a TLR 22 kit. I used it a few times with settings exactly as manual says. I changed a few things and after making a few changes the vehicle seems to spin out very easily. It's a mid motor mount TLR 22 and is used on carpet. I'm wondering why it is spinning out so easily now.

Here are the items I changed:

• From a 10 degree caster to 5
• From a 20 degree Kick Angle to 25
• From standard rear hex to +.75 on both sides

What impact will these have on steering?
Can anyone briefly explain what the caster degree, kick angle, and adding width to the rear axle will do to the cars handling?

Thank you for your help!

Hi,

I am running the same settings you have listed so far...

The 22 has lots of steering in its design but need some more info to check if its car set up or just driver being too aggressive/not used to 2WD driving style...

what tyres are you using front/rear?

what are your camber settings all round and mounting points/shims?

how have you set up shocks, mounting points, oils and what springs are you running?

Mine is set up to Nick Gurnell's set up sheet and then tweaked a little for my comfort... car is absolutely dialled on carpet so will happily help if possible

Widening the rear will make it worse.

@michael77 - Frecklychimp is spot on - there's a lot more to the set up than just the elements you've asked about but in answer to your points, here goes:-

Caster Angle - Best described as the angle of the king pins relative to the vertical plane. Think of it like trail on the forks of a bike. More Trail (caster) resists direction change. What this means is that more caster will make the car feel lazier on turn in but conversely, it will also want to stay in the turn longer - so it can 'hook' on corner exit.

Kick Angle - best explained by the main man himself Dyno-Dan. Click here for an awesome explanation.

Rear Hex Width - Affects the way that the car drives forward. More width can help in slippy conditions by giving the car more forward drive.

My favorite front end combination is 25 deg kick with 5 deg blocks. Rear Hex width I haven't played much with but you won't go far wrong with +0.75mm hexes in your box if you fancy it.

Hope this helps - but as Frecklychimp has said - your car is going to be predominantly characterized by many other factors including springs, pistons, oils and roll centres. Post your set up here and we'll try to help, else have a look on tlracing.com and try to see what the TLR team guys are up to - but beware cos most of them have got their motor still in a funny place
