Hi all.

There are many reasons why we do cold but it is the same with hot.

If hot then how many cool down laps did you do? What was the track temperature? Without good logging equipmemt its had to use hot.

In reality there are a guide only. Racers will often get the tyre SPREAD hotter but noviced will often get the surface hotter.

Use the above as a baseline ando what feels good. Ultimate pace can be found with the above settings.

Could you explain why you quote COLD tyre pressures? Surely its the HOT pressures that are relevant, as two people starting with the same cold pressures but driving completely different (say one slow and one fast) will generate different HOT tyre temps? I would have thought cold tyre temps are irrelevant, other than for a starting point to aim for hot readings when the tyres are actually up to temp and working  ???

I happily bow to your years of experience though, so if I'm just being thick I would appreciate you educating me  :) ;D

I have done it all. Settings that work on track to the best of the Atom ability:

14F/13.5R PSi Cold.

F 1mm Toe out across axle - 1.o Camber
R 2mm Toe in across axle - 4.5o Camber

Yeah could certainly be up for a bit of track time with Martin. Not sure when though as I'm fairly flat out at the moment. Count me in though.

I am £450 a day and I supply data, video and Radio comms for that. For an additional £200 I can bring my Atom mechanic along and do some settings changes trackside. You pay for your own track fees of course.

So if we aimed for 4-5 people that seems manageable.

Having some tuition off this man is definitely worth the money, i have had a number of days with him in the Atom and can say this is the best thing you can spend your money on before any mods, tyre pressures and a few suspension tweeks also improve the Atom but a day of tuition is the best way to get the most from your car you will be surprised how much more speed and time is left in the car..cant recommend him enough  :vroom: :checkeredflag:

I suggest Silverstone GP. Loads of run off for anyone who is chasing the last few 10ths and a great selection of corners.

Anyone interested in a club tuition day?

Yep, all of course dependent on date, time, price etc.

Hi all.


Yes it is all for the A048R's

Springs and ride heights are the last bit but honestly its really the last few 10ths.

Anyone interested in a club tuition day?

Re: Track day n00b - tyre pressures and suspension settings ??

by Peter255 » Tue Sep 06, 2016 2:21 pm

Interesting. Harder fronts! :o

What about spring settings?

I am presuming this is for a048's? Or what tyres does this refer to?

Cheers

In all fairness to vernonjones, he has spent a lot of time on track with the atom so you could do worse than take a look at his setup! Remember each car and driver is different ultimately though and part of the fun is finding out what works for you.

[quote="Peter255"]
But I've heard many conflicting "Factory suggested" settings.

And the handbook seems to suggest the same settings for all tyres. Is that true?
[/quote]

No problem.

The handbook can only refer to what comes with the car from the factory as standard. If you change the spec, or put your own tyres on, that would be impractical to detail.

There is only one factory suggested setting. Everything else is personal advice or hearsay, pure and simple (sic).

You seem to have found settings that suit you. That's great - I'd stick with them if I were you... (that's been my philosophy with my cars anyway)
