Hi Guys.
Free advice, ignore it if you wish!
Slot It GT/group C models come inline with a 9 tooth pinion and a 28 crown gear (yellow). This years SIC as run by Graeme Thoburn and the Molesley guys, is to a basic standard formula with hand out tyres run unglued on mostly plastic tracks.
On your old gloss track you have two main options. 1; Run the models standard(ish) and specify a Slot it tyre such as the P range. You will need to glue them on, your track when cleaned, will give very high grip levels and pull the unglued tyres off the rims!
2;
If you can't be ar-ed with cleaning the 'goop' of the track every time you run them, then the 'fish' foam tyre is probably the best option. No experience with running sponges on Slot It, but weight may be required to make them race-able.
Regards Bill.
P.S.John.
Have you a date for the 'Open Frame' vintage event yet?
P.P.S.
Happy and prosperous New Year to all at NLSME!

Hi Steve.
Your model looks very standard, as Slot It turned them out a few years ago. As Mick has said, the latest Group C and GT model have a dark grey, rather than black motor mount, this give a .5 mm 'offset' (hypoid) to the rear axle. If any of you guys buy S/hand versions and find them fitted with a light grey pod, this is a full 1.00 mm offset and should be run with the appropriate hypoid (white) gear. The .5 offset pod probably won't give a huge edge to the model, as this amount is close to tyre +/- after truing/sanding. The 1.00 mm pod will give a noticable performance (handling) improvement, so you may want to outlaw that one.
Cheers Bill.

Hi John.
Good observations, but in the context of very moderate power output, probably not applicable. On any wood track, even running the 'standard' 21k inline, I always end up with a little lead up front. Not a great deal, just 3-5 grms, but it is enough to balance the model and get rid of most of the front end lift when grip levels get high.
Cheers, Bill.
