Is there s secret handshake Craig

Forgot to weigh them sorry jez. Imagine its similar tbh.

Love what you've done with the RARB, i really wanna fit the one i have.
Nice you've still got a good petal, as the rear calipers are twin piston, so i thought you might lose that... But then that might be the travel you've gained.

Like the way you've done the C hubs too. Most of your photos a page back down work tho...

[Iain]

I think I can really feel the rear ARB working, it feels very planted.

Twin piston?! Looked like a single piston slide caliper to me?! Either way it has to be the travel gained from those as was running 4 pots before, so I think I'll be keeping my eyed peeled for a Corsa brake pedal bias box...

What pics? They're all working for me

[Benn]

Sorry, i was looking at the front caliper.

Well I'm booked into Blyton park for the 23rd so I've given it a good oil/filters service in preparation and filled the old beast up with Valvoline 15w50.

The brake pads were giving an awful rattle noise so I've fitted some Elise brake pad 'buffers' to quieten them down which seems to have worked!

I've also done a few tweaks to improve the gearing which I thought you guys may be interested in as it feels much better now.

1) With the internal shifter mech, you can get a better stick design that consists of a plastic ball rather than a ball and rubber washer:



Difference is obvious:



M12 threaded the end for my Quaife knob:



All fitted:




2) A better selector turret is available that bolts straight onto the F20 giving a better engagement feel

Original left, new one right:



Original turret moves around freely and sloppily as the main part is free rotating:



New one has a spring loaded nib fitting snugly into a groove giving you a much more positive feel when it moves as it is basically in one of three locations:



Moved for better illustration:



It's also got a spring loaded pin that you can use to lock it into first so you don't need the 'drillbit trick':



Part number for those interested:




Both of these mods together make the shifter feel lots tighter and more direct with better feedback when engaged. If you want the turret, look for a Corsa B 1.2 in the scrappy with the spring loaded pin!

You should make an Articles thread for those gear shift mods. That's important info that could help those who have already done the RJ linkage and internal shifter.

Nice work.

[Benn]

Very good info on the turret and stick.

[burgo]

If your proper stuck the turrets will still be available from vauxhall as the current corsa and adam still use this set up

[Malacin]

hi is the corsa c hub the same pattern as the nova? straight fit??? thx

[Iain]

Yes corsa stub axles go straight on
