Front wishbone and arb upgrades with added stiffness and extra caster. Basically the twingo has the povo spec clio style arb though its the same width as the 172 item and the wishbones are near enough the same size, just a slightly different shape and angle of mounting the lower ball joint. The Arb looks to be 1mm larger on the 172. I collected some parts off a friend and went ahead and fitted them up on the twingo. Jobs not finished yet as the inner arb clamps are a dick to do on the drive.

What a s**t day. 1.5 hours ish to swap out the twingo arb and wishbones in the rain. 5 hours trying to get the inner arb Bush clamps back on. One is there loose the other doesn't have a bolt in
the wishbones are very similar upon removal though the 172 items look to give a chunk of extra caster and possibly some extra width. wheel looks to.be about 10 to 15mm further forward. All needs aligning properly once I get the arb clamps sorted. I'm yet to drive it under it's own power yet but all seems ok so far. Once done it should aid handling a little.
Need to measure up the rear next, would be nice to be able to upgrade to a stiffer rear end with disks instead of drums. The twingo gt has the same rear track width listed as a 172 anyway so hopefully the beam will swap in easily.
