There were twice as many 104s than 103s, but this was more an issue of 104 vs 103, not an issue of foam vs rubber.

i agree, i like my 104 better also. it looks better, the front end is more adjustable, and it looks way cooler, but i think everybody is going back to the 103 because on some tracks it is faster when it comes to actual lap times. it seems easier to get a fast lap with the car. you can go fast with the 104, but its a lot more work. the 103 works right out of the box.

It really is sad that HPI has become a company that tosses out a car, comes out with a few hop ups and then completely stops developing or improving it.

A lot of people went back to F103's because they are easier to drive. You have that shorter wheelbase and wider track (20mm is a lot) that really makes the car stable. Though the F104 with a shimmed rear end and F103 front is really good too. You basically just have a long wheelbase F103 at that point. For scale appearance the F104 is great, its just not the fastest

How do you shimmed the rear of the 104 to make it wider?

Anyone can advise how I can make the Shimizu rubber to work. Both F&R sets are medium running on low traction asphalt. Track temp 40-45 deg c. The car just spins out at corner entrance. With status quo on setup it runs perfect on stock medium Tamiya rubber tires. Shock & damper on soft setup. Ride height 4.5mm.

Abu - Lightfoot posted a great F104 rubber tire chart on page 231 [chart link here]. You may also be in need of some chassis and radio adjustments. Great information posted by F N Cuda and APEX can be viewed on page 239.

You can buy axle shims that are commonly used for any Pan car and put the shims between the spacer and bearing on one side and between the axle and bearing on the spur/pinion side. You may need to widen the flats on the axle to ensure the set screws hold well when everything is shimmed. I added about 4mm rear track width. My brother added about 6mm (using a different spacer instead of shims) and found it worked well to make the car more stable.

See his setup here:

The F104 wants to spin out like crazy anyway, it's not a dialed racecar.

You need to play with ride height, T bar, shock setup, toe out etc. to make this car push when throttle is applied.
It will naturally push like a bulldozer entering corners and then go ass first as soon as you gas it to exit a corner.

Get the rear end low and the front end hi, motorboat style.

Get the softest rear tires and go from there.

Use brake to get it to turn in and expo to let it "ease" onto the power.
