Q: front caster

[andrius7]

hi all, i whant to someone to share with me about bigger caster on ph1.. what’s the difference compared to ph1 standart caster, what’s the difference in driving?

thank you

If you increase caster, the steering 'self-centering' increases and more effort is required to steer.

It is more complicated than that, though...:

Why are you thinking about increasing your caster?

i’m allready did this, just hadn’t time to test drive, i had one lower arm from ph1 172, and right side arm with different caster, i can’t get sport lower arm..

Ph1 172 & Non Cup Ph2 172 share the same wishbones.

These are interchangeable with the 172 Cup & all 182`s items with the revised caster.

It looks like you welded in whatever you have got there, and then redrilled them?

I swear you are like a Clio Rainman lol

Is there anything you don't know?!


(But, seriously, thank you for all your guidance and useful information on the forum!)

nothing is welded in, i redrilled them and testfitted

Have you had the car aligned to see the gain? I love how mines set up with 4.7 castor and 2.6 camber. Wouldn’t mind more on both though!

Hadnt time to clio, cos my son i sick at the moment and iam looking after him

That could be interesting, these are the Cup whisbones.

somebody did this before (Chip), did see gains , but ran into rubbing problems

Exactly.

Theres a direct comparison between normal 172 lower arm and 172 cup lower arm

 

[andrius7]

i need to try source cup arms after chirstmas.. because redrilled arms doesnt look safe

More caster gives you more steer negative camber on the outside wheel and reduces negative camber on the inside wheel. If you run lots of caster you shouldn’t need lots of static negative camber.

Basically, good caster setting will use both front tyres more effectively meaning more mechanical grip. The downside is increased steering weight due to increased mechanical trail or caster trail.

Did you ever run these arms with relocated ball joints and how did your caster angle measure up?
