ive had 4 gtis and a rallye with gti coversion , my 1st one was the fastest an could keep with my mates 172 cup until about 3rd gear then the clio would creep away, tbh i wouldnt say there was a great deal of differance between them but my 106 had a few mods an my clio is just standard,obviusly the clio is more responsive as its a 2 litre but the 106s are quick for a 1.6 with a few mods.
people really under estimate the 106s , i think its cos there so light ,
the clios are fast aswell i love mine , its all tucked away for winter now just going to sort out a few things that need doing and a few mods.
