I am looking to buy a clutch disc kit online for a 1979 FJ40. I was wondering if there is a big difference between the cheap ones and the more expensive ones. Are there any inexpensive clutches that are good or is it worth it to spend the extra money. Are there any brands in particular that you would recommend? I see Specter offers an Extreme Clutch Disc. Is there a big difference between that one and a normal one? Thanks.
