Fitting a later/quicker rack will bollocks up the vdc, steering angles are all different

Mate what do you mean by VDC problems?

The S206 didn't get quick rack steering due to the suspension setup it runs (doesn't need it).

JdmSti2006

Vehicle Dynamics Control
tracktion and stabilization control , in theory most upgraded suspension parts could take an effort on oem VDC setup ,doubt car will notice it with quicker rack

It does.

Mate has this been tried by anyone having searched I can't seem to find any evidence one way of the other as to whether it would cause an issue or not. I basically need a new rack and the price is the same for 13:1 or the standard 15:1 rack, but obviously the 13:1 qould feel like an upgrade.

Look up US forums, that's where I first read about it as I wanted to do it with mine for exact same reasons then was put off by fact you have to drive with vdc off if you want the car to not do anything random....its all down to the steering angle which is used in the vdc calcs, the angles are then wrong with the new rack.

there is a fella local to me done it with his and has issues, obviously the issues are only present when you force the vdc into action...but for me I wasn't for doing it.

what’s wrong with the pump?

STI VI

Thanks Don!

STI VI

Its leaking apparently

Check it's not the small O ring on the pump that is leaking; a cheap fix as pumps are v dear

forgedmarco

iTrader: (10)

as hedgecutter has said you can buy o-rings to service the pump.

STI VI

great thanks guys any part number for the o ring then I can try that first

forgedmarco

Not sure if UK is the same but usually the first one to change in the JDM model is 34439FG000, ICP list seal kits for earlier models also so might be worth asking them.
A new crush washer is also good practice and the bolt torqued correctly.

STI VI

haha thanks where's Don when you need him 😂

Is it true that the VAB STi has 11.1 ratio? Is that JDM only or also U.K?

forgedmarco

iTrader: (10)

They're 13:1

apac

iTrader: (2)

Maybe it was just the TS type RA.

forgedmarco

iTrader: (10)

Yes they had curved tie rods too, not sure what benefit they have?

s207 & s208 got the 11:1 racks

STI VI

Thanks Gents super helpful as always and saved me money if these O ring solves the leak as the pump isnt keep and at the moment with the new clutch this is turning into a money pit
