V-one-RR sp belts (192) for the rear and MTX3 (201) front belt. I can't say that these belts are stronger until I run the Bando belts. These are belts that are at my LHS.

if you want to free up the front and rear belts just flip the stock belt inside out and leave it over night in wd40.

Well, I finally had a chance to run my car at the track. The car was so easy to setup and I was more consistent running this car then my CD3. I ran a diff (100k) and Rear Diff (30k) and the car was smooth. I am very pleased with the buy.

Default GPX PRO 2005 CHAMPION

The GPX PRO won the 2005 championship in Cyprus.
It looks like HOBAO did a good job on the car.

Francis M:

I am currently running the RRR and am interested to hear your feedback with the GPX4 vs the RRR. I noticed you were talking about soaking the belts in WD40, are you still running these belts like this and did you do any other changes to the bulkheads or anything to free it all up? I am looking at another alternative to my RRR that won't break the bank

Look forward to hearing from you all shortly.

I had a couple of friends drive my car and they both loved it. One of the guys ran the RRR, and MTX-3, at one time. He now runs the MTX-4, said the GPX4 is very comparable. I let him set it up as well, just to validate this comparison. They were equally impressed with how much these cars are worth on the market. Attached are some more pictures of my car. I added a 5th body post for more body support. I am at the point of fine tuning my car at the track every week. Another friend said it right, "you can't go wrong with choosing any of the major brands on the market but having your lhs stock parts is a definite plus."

Although this car has less adjustments than the RRR. It seems to be more in the ball park set up wise when i go from track to track. the main difference i use from stock is i use hong nor spring wich is the same as associated springs. I always start with yellow front and red rear or copper rear and just mess around with the droop. I haven't done anything to the bulk head. another thing I changed on the car is I used mugen aluminum hexes that locks and tamiya shims same size as the 10x15 bearing behind the hubs to get rid of side play. As for saving money this car has saved me a lot of money since making the switch. I really liked the RRR but could not afford to replace the pinions along with the out drives every two meets.

three50zx, i noticed some carbon fiber post stabilizers/stiffeners and bulkhead ( on top of the foam bumpers). Are these stock parts from the kit or are those upgrade parts?
