BRM Alfa GTA 1300

[Movintage]

Hi guys. I hope everyone is safe and well.
I have one of BRM’s new Alfa GTAs. It’s a real beauty! I’m trying to find out if anyone knows of silicone tires that will fit? Looking at the Alfa’s parts list it uses the same rims as the BRM Opel Kadett.
Best to all,
Eric

As an update, I tried QS RS75. They fit and work fine as the width is perfect. However the RS75s are shorter than the stock BRM Rear rubber. The car can definitely handle a taller tire. I mic’d the rubber at about 23mm.

Does anyone know why the revoslot cars have a 21k motor and the BRMs have a 19k motor? I presumed the larger cars would use a faster motor.
and for that matter, why does revoslot use brass/regal gears but BRM uses nylon? Again, I presumed larger cars would get “better”/“stronger” parts.

These are different companies building their own products the way they want to.

Car looks great! I only use rubber on my track - BRM rubber for both the NSU and Mini.

A friends runs the same tire that the Revoslots use 1501/2 silicone Super Tires. They also have the built up area in the middle so no airgap.

Thanks Dogsbody!

I've got these two plus a Mini. The BRMs were great out of the box. The TTS took a bit of work to make it quieter and smoother.

I'm looking forward to the BMW 2002 coming at the end of the month.

PI added the Alfa to my expanding BRM lineup of Group-2 cars. I already had the Fiat Beretta Abarth and the black Martini Mini.
All are super fun cars to race. While I haven’t found any benefit to the rear axle camber setup on my Abarth and Mini, the independent front camber axles on the Alfa make a big difference in taking turns faster and deeper.

I like the matte Mini!

Do the Alfas use the goofy camber on the front end like the Escorts?

[WB2]

1:1 yes. 1:24 - why?
Independent rotation much more important.
If one wants that front camber to really perform, get Frankenslot front tires that are tapered. Point of road contact is much farther out, essentially widening stance of car.
The Tacoma boys said the BRM taper ground rears transform the rear camber cars. All of the rubber is on the ground.

Unfortunately the club I race with runs all stock except for silicones on the rear. But good to know, Thx

There is a shop in Canada that stocks Frankenslot items but didn’t have the tires.
At one time Cincy Slots had a few of their items.
I thought of making my own tires by using a tapered block on my Tire Razor but thought is as far as it got.

Yup.
