HPI Cup Racer 1M

FYI, Robinson racing spur gears fit the cup racer. This is the one I used when I raced it.. It's 60t and 48p. They also have a 65t / 48p

As for the cg roll on your CR'r, be sure you have your wheel hubs in the correct order, I believe there is a subtle difference between the left and right sides (I've accidentally installed them incorrectly). Also make sure your chassis isn't too high off the ground, -I am at work now, but think my ground clearance is around 7mm ?? I can verify later. Adjust the camber and shock spring and oil weight. Your CR probably just needs to be tuned correctly, -they shouldn't roll and should handle very well.

Hello!
Im a Cup Racer enthusiast from Norway. I'v found that also the 3racing 48 pitch spur gear fits the cup racer. They have the range from below 60t to way over 70t. The spur gears is a little bit slimmer than the original but they fit on the hub nicely. How durable they are i do not know, have had three packs through a 68t and it holds up fine. Just a heads up.

-Thank you Anorak!
This is great info, especially as the CR has long been discontinued and there are still many of us out there who love and still drive our's.
My CR has been on the shelf all summer as I am no longer racing it competitively -there is no class for it where I race. The closest is the "Mini" class, but it is strictly for Tamiya Mini (M01-M06). So my CR is now strictly a parking lot racer.

I once stretched a set of Tamiya Grasshopper tires over the MX60 wheels:
You'll need to raise the body a considerable amount if you want to make a rally out of it:
If you're simply looking for a better performing tire, then I'd highly recommend switching over to standard 1/12 Touring wheels which are 54mm in diameter, my favorite brand is the RIDE which offer belted slicks with a very thick tread that is nearly twice as thick as most stock tires:
Here are OFNA JL12e slicks:
Note that you need to buy the standard 54mm wheels from RIDE, although the RIDE tires can be stretched over the MX60 wheels, they will perform better on the RIDE wheels.

ha, an exotek chassis ...good luck, ...search ebay maybe one day you'll get lucky?
I have a lot of spare CR parts still in their bags (including the disc brake set). But not the Exotek chassis set. ...I did have a couple of the HPI CR carbon fiber chassis NIB but sold them ...the one I have I put on my CR. I think you can still find them on ebay or amazon marketplace occassionally.

What a coincidence, just took my CR out for a little driveway bashing the other night for the first time in about 4 years. Are CR tires no longer available?
I almost forgot what a fun little car this is!

MX60 tires are getting harder to come by these days, they are no longer made, so I would stock up them while you can:

Personally, I've had much better luck with the RIDE tires which are just a pinch smaller in diameter... here are a set of RIDE tires to get an idea of what they look like:

I just purchased a Cup Racer kit from a forum member for my BMW 2002 Turbo project, and was wanting to trick out the chassis as well.

My cup racer is apart for odd grinding noises in the rear. Also it keeps letting the right-rear drive loose at the hub. Has a Lancia body on it, so I assume that takes a toll on its reliability :-D *
*Daily drove a Lancia Scorpion for years. Great car once previous owners 'improvements' were removed.
