Renaultsport Twingo 133 1.6 16v with no expense spared! Some very nice extras such as the popular and desirable Team Dynamics pro race 1.2 15" with continental tyres all round nearly new only one low on tread as tyre pressure was low and never noticed but will replace it before sale, Eibach...
The problem you are having is the size and weight and tyre profile. I had the same issue with my girlfriends 133, dropped to 15" team dynamics pro race 1.2 on continental tyres it now drives like a different car so much better!
I am struggling to find these readily available anywhwew also, but gonna go for new arms on both sides i think, people who still run oem 17" 133 wheels i feel the wheel weight and small tyre profile have a massive impact on the life of your balljoints also as its extra load on suspension parts.
