Tyre Inserts?

[FrogPrince82]

Hi All,

I was just wanting to ask the wise sages here of what inserts I will need for my Yellow Mini Spikes?

I take it the medium firmness is the best?

Also, are the standard size foams the best, or are the Schumacher "Tubby" foams worth a look? I'm guessing they help the tyre keep it's shape more with out them becoming too hard a ride (e.g. as if using firm foams). But not sure if this is a desired effect on our slippery wood flooring?

Looking at maybe putting an order in, unless the success/popularity of the 3 rolls of carpet means we will be running higher grip levels for the next few weeks!

Thanks

Usual. Regular medium foams
Mini spikes still work on the carpet. But wear quicker.
Yellow mini pins and medium inserts for carpet.

I generally use medium "tubbys" in all my tyres, hard to say what tyres are the best to use, both got there pros and cons, think Jeff and clarky were on spikes all night and generally they were the quickest,Chris P was on used pins from Worksop, he tried spikes but soon returned to pins, he wasn't slow, I tried both pins and spikes, setting my quickest time on spikes finding my car easier to drive on them

Cheers for the responces.

I've seen the closed cell type foams too. I always thought they seemed a little expensive, but do they provide any performance benefits? I've seen the tyre removal techneque using nail polish remover so may invest in some if they are reusable through this method and are beneficial.

Does anyone know how they compare to the Tubby and standard style of inserts???

I always use Schumacher Tubby inserts. You'll get slightly more grip low speed from softer inserts, but the tyre will collapse on the carpet sweeper. I'd just stick to Medium tubbys.

A bucket of industrial strength acetone (not nailvarnish remover) is what you're after for tyre removal.
Cut the tyre, remove insert (you dont want the insert in the acetone as it ruins the insert, then plonk the wheel & tyre in a sealed bucket with 3 cm of acetone in the bottom. The vapours wil loosen the glue.
you can get the acetone here:

I can pick some up for you if you want, (they sell the sealed buckets aswell) as its near my house.

I used minipins on Sunday, but I think mini spikes would be easier to drive. My car was very 'tippy', often on 2 wheels, and quite difficult to drive. You can see on the video from the A final how often my car is on 2 wheels

I tried new mini spikes, for one lap, but they wouldn't have been any good until they'd been used for 5 minutes to wear them in, and I didn't have that run in time, so I went back to minipins.

Thanks Chris.

As the mini pins are grippier on carpet, and guessing that this because of the smaller pins biting into the carpet rather than them flexing to generate grip like mini spikes, would they be better with a firm insert to help them keep their shape and stop them creating excessive grip from flexing?

Yep, you got it ... but they will create excessive grip on the carpet.
The minipins are like velcro on the carpet, and a little slippier on the slippy floor than mini spikes.

I really would recommend minispikes over them .... you have to be wide awake with them on your car.

Thanks again Chris

Maybe if I can get to your level of driving I can begin worrying about driving a car so quickly on the edge, at the moment I'm just trying to get to grips (like the pun? ) with learning what the set-up changes do, getting consistent lap times and not crashing so much when in traffic

Thinking of doing the regionals to help bolster my practice and experience too so all the info I can get is helpful, hence all my questions on oOple!

Do the regionals, it will be good fun.......!!!

To be honest jaime i havnt bothered too much with setups "UNLESS" im really struggling with something..........Ive mainly concentrated on having the right tires and racing as much as i could !!!

Changing your driving style also helps out loads as well, instead of making so many changes.

At one point i was racing 3 times a week which really helped me out a lot.

I could be holding myself back by not messing about with different setups

Alright chris could you get me some acetone if you dont mind please ???

How much would you recommend also ???

Cheers

as Dexter has said, practice practice practice. dont get stuck on setups and trying different things. just concentrate on getting round without crashing and the rest will follow. but the tires really do make a big difference. for seaham yellow min spike and medium foams is the most drivable option. bog standard medium, answer RC foams which are cheap as chips from MB models do the trick.
doing the regionals is great fun and a great experience, highly recommend that you do as many as you can.

I saw there were some dates for the NE regionals on the board on Sunday, but forgot to take down the details

Does anyone happen to know what they were so I can sort out getting around work?

Is it the standard width fronts or the slim ones that are best at Seaham for the Schumacher mini spikes???

I'm guessing that the standard may have a bigger contact patch, but the slim ones will have more pressure being applied to them, so not sure which generate more grip on the slippery surface.
