Default Body cut for rear tyres

Guys,

To prevent the rear tyres from being oily because of the exhaust smoke, I did not cut the body for the rear tyres.

Also I thought this would improve the aerodynamics as well.

What would be the difference in the car's handling?

Is this advisable?

Tx in advance for any feedback.

I believe all the wheel wells have to be cut out. they even list a maximum diameter(roar rules). Do your wheel nuts rub on the body????

Roar rule

6.1.11 Wheel cutouts are allowed on the side plane of the body. They may not extend into the horizontal plane of the body. Wheel cutouts may not exceed the dimensions specified in the relevant class rules or specifications. Wheel wells must be cut out if the original vehicle ran that way.

I understand that you do not fall under roar rules

Pass you soon...

Tx for the clarification.

Haven't thought about the rules.
I work and live in Dubai, the United Arab Emirates.
Unfortunately, we don't have races here following a certain type of rules.

I did it just for pure practical reasons.
The car looks strange though.

I don't think it's practical. Sorry...

I have seen some of the guys here who leave the wheel cutouts.
One only trims a little off the bottom of the cutout for a little clearance to the track.
Another cuts a small hole so that he can still access the wheel nut to remove the tyre.
One thing you should check though, is to ensure that the exaust stinger protrudes through the side of the body so that the oil etc is expelled to the outside.
If not, you may be getting oil, fuel running down the inside of the body and onto the tyre.
Running with no cutouts will be fine, but will make it a little harder to fit fresh tyres.
Aerodynamically, it may make a small difference too, but not a whole lot.

Reminds me of the cars in the 1950's that many had Fender Skirts on the rear wheel wells. Whoops.... showing my age.

BTW.... that is a nice paint job!!

See you at the finish line,

If the Pipe is mounted correctly it shouldnt make the rear tires oily... I haven't had any oil on mine, and if it does get on it doesn't make a difference because the tire is moving at so many Revolutions that the oil cannot stick to the surface

Just my 2 Cents

also, i dont really reckon that oil from the stinger really makes the tire less grippy.

there are people who put petrol compounds on foam tires to make them more grippy. however, i'm not sure if castor has that effect on foam.

what do you think?

I've ran 8th scale and 10th scale and even if there is any oil on the tires it doesnt effect the grip at all... it may mix with the track traction compound and even bring it up... if oil made tires slippery and uncompetitive then manufacturers would have made the stinger stick way out of the body
