OK suspension. Not really had a chance to try them out properly, but roll is reduced and the damp and rebound is much improved on these gas shocks over the standard ones. The rears are shorter by about 20mm the fronts the same length as standard but the piston is notable a fair bit thicker.
I found the standard suspension to be pretty awful, the H7R springs not only dropped the car but improved roll considerable and TBH on a nearer standard car would have been good, but we felt on the improved performance of this car a better all round set up would improve things again, and it has moved the game on. We paid pretty much what you did from a UK company but all they do is then order direct from KW Germany as they are a reseller, so do not stock the items themselves, like many companies now, we got ours in 3 days.
The reason for the 240mm disc is two fold, one it means you use front Cento discs on rear, so the offset is not changed so you can reuse standard hub, though these need custom brackets to make them, see group buy. As for callipers well anything from Punto GT to what we used Marea 155HLX or whatever its called fit though they are bigger than the Uno Turbo callipers we have also used, so again like the front callipers there are at least two different types on the go by Fiat. So we have the turbo Cinq with the earlier smaller Punto GT callipers and UT rears, and the Sei on late spec bigger Putno GT callipers and later/diff spec bigger rears. These cars unlike earlier UT do not use separate brackets to attach the calliper.
Why previous conversion's including the two I have done used 227mm discs as this forms part of the conversion using the brackets found on UT's, these brackets are NLA and as such difficult to track down unless someone is scrapping a UT. You can't just bolt on the discs though without using UT hubs as well to get the correct offset, not only for the brake disc but for the wheel, so what at first may seem a cheaper option of getting scrapped UT stuff can be more expensive as hubs are not cheap at about £35 each as most of the hubs off UT fall to bits when you remove them, well 3 out of 4 of mine did, so we bought new, plus often the callipers are in need of refurbishment, we got all four of ours done at BigRedd.
The custom brackets are really similar to the genuine UT brackets only the calliper mounts are spaced out about 10mm or so to clear the bigger brake disc, if going to trouble of getting them made, it makes sense to get them made to fit the 240mm disc.
It should be noted that the Panda 100hp, and new 500 Sport run this set up 257mm front vented discs and 240mm solid rear discs and both these car tip scales at 930+ kgs, so on cars weighing about 800-820kgs makes them stop very well, vast improvement on the frankly awful standard set up, oh and you get a wonderful handbrake.
I hope that all makes sense and reads OK as just sticking down what I can remember.
