Crap overpriced new performance parts

[Toby]

the shafts of the fiat argenta,all you need is a set of spiders and the the shafts.the spiders weld them in the diff spiders cage and the shafts all you need is to do the holes for the wheel studs. but for fiat 132 shafts that are a lot stronger you have to make a spool,here we got costum made

 

Thanks mate. Tell me is a spool used out there much and is there any benefit other than fitting alternative shafts from using one?

 

Can you quantify any drag time reductions you would expect from using one over a std LSD?
