Any update on the prodimex shifter and on the interior refresh ?
Just bought a low mileage 340R and some of your initial impressions are the same , spongy brake feel ( not sure if my car is fitted with pagid RS14 or something else )
and usually the RS14 are a really agressive brake pad on other cars , the gear lever feels like there isn t much return spring , and the interior paint require a refresh.
I ordered a prodimex shifter ( just to improve the feel even vs a restored oem shifter ) and some elise parts cables ( I think the old oem cables could be full of old grease and
the elise parts cables will be new better and replace the oem rubber bushings with something better and more precise )
On my 340R the suspension bushings and everything related seems in really perfect shape , and as it s a light car the oem bushing can be ok if in good condition.
If you require to replace those I would still fit either powerflex or elise parts polyurethane bushings , or if you want for more precision or track usage you can use Nitron or elise parts
uniball metal bearings , they are not really necessary especially for a road car , but still I used them on a 260 cup and there were not any noticeable increase in noise or vibration.
The Koni OEM dampers do feel good and well balanced , and as suggested they do not make them anymore so you can probably find a place to get them serviced and revalved
if required ( maybe at koni ) and if you replace them with something else keep them of course.
There are other suspensions that are really good and even better ( Nitron, Quantum, JRZ, Ohlins, Intrax , AST , etc ) and if you want something more specific for track or better for irregular roads you can get something better for sure , but of course aftermarket suspension will not necessarly be better valved and balanced for your expected use , and the koni are already good.
