    Default s3 hubs versus si hubs

    can si hubs be made into s3 hubs by changing the centre to suit the gti 1.9 drive shafts. i want to get the wheels tucked in on the front of my s2 but keep the gti drive shafts. i am only guessing here as i was told si hubs make the track narrower when fitted to a gti but you need to use si drive shafts?

    Si shafts are the same as GTi S1/S2 shafts. The S3 shafts are the ones that are different.

    Yes, more splines and larger diameter on the wheel end, same as 405 shafts, but shorter of course.
    Inner is the same in all cases.

    Are there any advantages to running SI hubs on a Series 1 or 2 car?

    Yes, you can fit 306 brakes, including GTi6.

    And that would require a larger master cylinder?

    Standard ones no, for the GTi6 you may need a larger cylinder as these can be too sensitive. Also, you may then need to change the rear compensator to bring the rears up ro the level of the fronts.

    You can also fit 206 brakes, in their various sizes. I think you definitely need to move up to a 22mm 306 m/cylinder if you put on 266mm brakes.

    Default si hubs

    so you can fit a variety of non std gti brakes and it will make the front track narrower by approximatley how much? my c5 rims only just stick out on the front guards.

    Default How do you make a table in VBuli

    Reproduced without permission - because I can't remember if it was the UK or another 205 Board I saved it from.

    Hey - It's about sharing the grey stuff.

    Hope it's of use to you djvu205 as I'm a bit slow off the mark these days.






    Driveshaft lengths and splines

    For Peugeot 205 and 309


    "I made this table to see what driveshafts I would need for my conversion. 309 GTI driveshafts aren't very plentiful in junkyards. Also, I wanted to know to who I could sell the driveshafts I no longer needed. In this table you can also see what hubs will interchange without swapping the driveshafts as well. Could be useful when doing a brake swap.

    Note that a different line in this table means a different driveshaft (part number), even if all numbers match. There's one exception : diesels use the same driveshafts as 1.6 automatics. For instance an early 205 1.1 has different shafts than a 1.4 of same vintage. Probably the 1.4 axles are just stronger, but they will interchange. For example, I'm now running diesel shafts on my 309 and they fit fine, only they might be a bit less durable. Not mentioned in this table is the fact that ABS equipped GTI/CTI versions have different driveshafts too. That must have something to do with the wheel sensors, they probably don't interchange. The longest one (right hand side) always has a centre support bearing, except for early 205's that have equal length driveshafts without a centre support bearing. Those cars are also the ones where gear oil and engine oil are one and the same.
    Length figures are overall length, but compressed to minimum. Model years span roughly September thru August, so the '88 model year begins September '87. Thanks to the verbose catalogue at the parts store!"

    Perhaps we could check this for accuracy ( and format it in a table so it's easier to read )
