So I've done plenty of research and reading up on the Saxo gear linkage system, and having done quite a lot of work on my VTS today thought I'd put up some info and pictures to help anyone who had the same problem I did.
First off for anyone who isn't familiar with it, here's an overview of the Saxo gear linkage:
The reason there are so many problems with floppy gearsticks is that every single link and ball joint in the above diagram is prone to wear. The main culprits are normally:
The large circular bush on No. 1, Selection Bar Part No. 2414A7 £36.87 +VAT
The spherical nylon ball on No. 2, Control Return Part No. 244965 £37.19 +VAT
The socket cups on No. 4, 4 and 5, gear rods. Don't have a part no. for these as uprated replacements are widely available from the likes of Kam Racing/Pug1off from £39.00 which is cheaper than main dealer prices.
The upper No. 4 gear rod connects to a control arm on the gearbox. This is held onto a spindle in the box by a Roll Pin, Part No. 250924 £0.32 +VAT
Not normally in need of replacing, but the housing at the base of the gearstick can be replaced with a quickshift from the likes of Compbrake, GMC or, for a bit more money B&M. Although you'll be able to dramatically improve your gearchange just replacing standard items, my GMC quickshift has made my gearchange feel heavier and more solid compared to the standard housing, as well as obviously being adjustable to reduce the throw of the lever when selecting gears.
I've replaced all of the above on my car and it's made a massive difference, my gear change literally feels like brand new, it's smooth and slick and not notchy like it was before, with no movement from the gearstick once the car's in gear at all, whereas before I could wobble it side to side. I can confidently throw it into whatever gear I feel like without worrying about crunching or missing gears now, which is just what I wanted before I took the car on track.
Anyway enough talking, onto the pictures!
