The Kyosho Inferno GT cars have proven to be very durable in our racing program at SS Raceway.
I personally haven’t broken very much with my IGT car after nearly 3 gallons of racing. There are some maintenance items that I check & replace on a regular basis. These items are:
Clutch bell bearings. The stock bearings are “needle bearing” type; I’ve replaced them with 5x8x3 un-flanged standard type bearings.
The standard aluminum clutch shoes require the same attention as in off-road racing. As the aluminum wears, it mushrooms its edges and they need to be cleaned up with a razor knife. I’ve been replacing my clutch spring after each gallon to be on the safe side; clutch spring part #92405.
The Kyosho #KC45 “carbon” type clutch shoes also work well too. They provide a little more “stall speed”, a little smoother engagement and some more RPM too.
My IGT came equipped with the new 15/19 clutch bell gear set. Some cars have the original 14/17 set. If your track has a lot of hi-speed sections, I’d suggest upgrading to the 15/19 set if you have the smaller gears.
The spur gears are plastic and mesh is critical. Last weekend, I was helping 2 new IGT racers in the pits. After getting them set-up and missed some of my qualifiers, I started out in the B main. After winning the “B” and bumping up to the “A”, I felt good about my car. I started at the back of the A main and with less that 1 minutes to go, I stripped 1st gear after getting to 3rd place, only to DNF in 5th place.
So the moral to that story is, check your mesh & engine mount screws. LOL. An extra #GTW20-2 gear set should be in your box.
As far as factory options, here’s a few that I think any IGT car owner should look at.
IFW330 SP Brake Pads, IFW122 SP Brake Disc, IFW108 SP Upper Rod, IFW2 SP Tie Rod, IFW124B Suspension Holder Set, IFW104 Front Sway Bar Set. I’m sorry I don’t have the part number for the rear sway bar on hand & front support chassis brace, but I’d also make them a racing upgrade too. Other than that, the IGT is ready to rock!
The Kyosho Inferno GT is a great performer and shrugs off just about any impact while racing. It is a lot of fun to drive and looks like a real car out on the track.
