Release in 1995, the Esprit S4S fits between the 264bhp S4 and the Sport 300. The S4S is designed to drive like a 300 and ride like an S4. No increase from the standard cars 2.2 litres has been necessary to find the S4S's extra power; indeed neither was it the case with the Sport 300. Improved gas flow dynamics and enlarged inlet ports and valves are the main cylinder head modifications. A hybrid Garrett AiResearch T3/60 turbocharger and altered management programme endow the engine with even more torque over a wider spread. Of the 290lb ft maximum, 80% is ready to be unleashed by your right foot anywhere between 2500 and 6500rpm.
The S4S takes the 300's rear wing and wheel arch extentions and gains OZ split rim racing alloy with 245 and 285 section Michelin tyres. Big ventilated discs and calipers are now by Brembo and provide all the stopping power you need to haul in 300bhp.

UK Esprit S4s Wheel Refurbishment Advice
Basically I searched everywhere for a company that could refurbish the wheels and most importantly re-lacquer them, I found a company that can refurbish them, but they won't re-lacquer them as the process is very complex and if you don't get the amount of lacquer spot on it will crack. I've heard of people stripping the splits down themselves and undoing every single bolt and doing a DIY job, I talked to OZ in the US and they seriously advised against this as if you don't get it spot on the stresses passed thought the wheel can make it buckle under high speed cornering, definitely not a good idea.
Other option is to buy a new wheel at £500 a go.
So anyway after lots of research I ended up getting one front and one rear refurbished at a company called "Pristine" they did a great job and the wheels looked the nuts absolutely great, problem is they were not lacquered. So to keep them in good condition you need to wash them regularly and if your leaving it for a week or more you just need to spray some WD40 on them to keep them in good nick. If I had the problem over again I would do exactly them same and get them done without the lacquer.
I paid £110 + VAT per wheel to get the tyres taken off, wheel refurbished, tyre back on, new valve, and balanced. It took one week from dropping them off to getting them back.

Do not worry about them not being lacquered, look after them and keep them clean and they will be fine, but make sure if it it's left outside for more than a week you spray the wheels and if possible don't put them away dirty. Once you get them refurbished they will look like new and are the dogs bits, look very cool. BUT KEEP THEM CLEAN!!!!
