ummm if you have the g4s, you have the ufo clutch which is arguably the best clutch on the market, so I dont know why you want to upgrade

I added the speedshot front end to give more adjustability with roll centre and the diff is much easier to access.

If you don't have the ED transmission then that is another great upgrade.

Bud id suggest getting out with teh car and getting stick time under your belt before making hop ups.
If anything on the G4S is needed id suggest starting with getting 18t pinion for the first gear and spare spur gears to play around with gearing.
It would be also good to get the 20t brake and side pulley with 26t front side pulley this makes the cars bottom end more responsive.
as for the clutch just a hard clutch spring is needed like the 1.8mm black Kfactory clutch spring or a Mugen super hard.For the rest of info you need check out or ask questions on teh G4S thread ,the guys will help you get sorted

rcrev,

Take your time practicing with the kit first. Play around with the clutch settings such as gap, end play, clutch weights, spring adjustment and find out how all this come into play. Just because the next guy got the Mugen spring doesn't mean you have to. The Mugen spring is well suited for high traction tracks. If you put in your the Mugen spring and your track (or parking lot) is slippery, you'll likely do a bunch of donuts. If your track does high grip, you will see a more punchy response, and the car will take off like a rocket. (given that you set your clutch correctly). I've been using the stock yellow spring myself. I do have the Mugen hard spring, but the yellow seems to work for me.

Bud just as Dnitro said and i said initially ,get out and run the car and be prepared to play with settings to learn and see what the differences do.
Other suggestions i made is if you get sorted and are looking for a bit more performance they would work but as D said its dependant on the type of track you run on.

you must have the RTR G4S. you may want to get the UFO clutch for sure. or you can try to play with finding harder springs for the clutch you have. some times you can find the 1.2 springs or try to lighten the 3 shoes. like drill small holes in the teflon shoesto lighten them. this will make the engagement later.

If its a normal 3 shoe clutch then get some 1.1mm springs and some ally shoes.Put one ally shoe in the clutch with replacing all springs to 1.1mm ones.

Let the engine high idle a full tank and then run 4/5 tanks at half throttle and graually bring it up to temp/performance.You could also do the Cyrul wide open throttle method ,it is worth the extra effort.

dont see why it should be hard to find as most 1/10 and 1/8 buggies use them ,even the gas trucks.They are not car specific so most hobby shops should have in stock.
Id suggest trying 1mm springs first and then 1.1mm.
