Hi Gents, I need a new rack not sure if the stanndard rack is 15:1 and to fit a spec c 13:1 or VAB steering rack, any advice here and does any one have the relevant parts numbers?

Cheers

 

Think newest VA sti one will fit,read its the best one to have

 

As requested:
Steering Rack assembly
G22 RHD models MY08-14 UK/Europe
Lock to Lock : 2.8 turns
Part number: 34110FG040

JDM G12 Rev A-E STI - 34110FG010
Rev C S206 - 34110FG040

V10 RHD models MY15-17 UK/Europe
Lock to Lock : 2.4 turns
Part number: 34110VA103

JDM V10 Rev A-D STI - 34110VA103

 

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

 

2015 rack fitted to blobeye,its doable and its better than newage jdm one etc

it's doable on GRs also but bollocks up the VDC

 

Thanks Don your a star mate!

Question assume all these racks fit without mods, do you know the difference between the JDM rack 34110FG010 and the S206 rack 34110FG040? and what ratios are theybelieve the JDM is 13:1 and the standard UK rack is 15:1 or my understaning not correct? cheers

​​​​​​JDM G12 Rev A-E STI - 34110FG010
Rev C S206 - 34110FG040


Saw this posted on another forum is it correct mate?

​​​​​​GRB 2008 STI JDM : 2.4 Turns Lock to Lock (Steering Rack Part: 34110FG010)
GRB 2008 STI Australian : 2.7 Turns Lock to Lock (Steering Rack Part: 34110FG040)

 

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).

 

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.

Gents apprently I need to replace the steering pump as well now, does Don or anyone else have the part number for me please

 

 

what’s wrong with the pump?

 

Thanks Don!

 

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

 

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

 

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

 

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.

 

haha thanks where's Don when you need him 😂

As per Forgedmarco ^^^^ 34439FG000 shown below

 

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

 

They're 13:1

 

Maybe it was just the TS type RA.

 

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

 

s207 & s208 got the 11:1 racks

 

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
