Cadwell Park in April - 3 degrees, snow, sleet and rain.

Last time I was there in July, was one of the fastest there in the glorious sunshine. Today, I was one of the slowest. Embarrassing. Frustrating.

I know I should have been smooth, but that just became slow. Car just wanted to slide in every corner - running Federal 595 tyres which are supposed to be okay in the wet.

Maybe I should take up golf.

I've not done a wet track day, but I have been caught in torrential rain on the motorway a couple of times an it was highly unpleasant! More a survival challenge than any fun.

I don't know who told you Federal 595 are good in the wet, they are like hard plastic when cold & a 7 is just not going to be able to get heat into them in the wet.

I did a very wet track day at Blyton Park a few years ago in a R1 engined MK indy R.

I spent more time going sideways and spinning than straight hehe

Its likely mostly my driving ability, but i just couldn't get any traction!

Also got very bloody wet!

Hullavington a few years ago was the site of my first track day spin...



It really took me by surprise!

What tyre pressures were you running?
Remember that in the wet you need to increase pressures.

Caldwell in the wet is a cracking circuit, really keeps you on your toes - especially over the mountain when the car goes light!

16PSI. I understood that you drop tyre pressure to increase grip - they heat up quicker and have a wider contact patch??

Any rate, I don't think tyre pressures would have helped. A bit more driving talent might!

I've found that the light weight cars always struggle in the wet, I'd love to know if there's a solution.

Do you mean understeering? Tyres and tyre pressures can help significantly. Also you could look at removing the front anti-roll bar if understeering, and if they rear ARB is adjustible you could be adjusting it.
In my previous Westfield I used to throw on a set of skinny avon CR28 turbospeed and they were phenomenal in the wet - the closest road legal thing to race wets I've ever used.

I know it is a very different car & what was the answer for me may not be the right answer for you, but, I use the best tyres that I can find on the road which double up as my wet set up & then Nankang NS R2 for the dry.

So CSC 5s/F1 Assy 2/RT Sport Max 2 for the wet/road, I gather Rainsport 2 are well liked for this too.

Buy yourself a tintop for wet days?

Car wanted to oversteer as soon as power applied - unless really gentle.

595's are ok in warm dry weather but as said they are rubbish in the wet or cold. NS2R are ok if you get the 120 or 100 compound. For a 7 type car there are plenty of tyres that will make 595' s look like wooden blocks.

Why would even care if the car isn't fast in the wet? You're there to have fun with the car. You're not a works team with wet / dry setup's chasing tenths for a podium...

Personally, I'd think Cadwell in the wet in a Caterham sounds like the most fun I could ever have...

Can echo the comment about the CR28's. Also had them on a Westfield at a soaking Silverstone trackday, which was eventually abandoned. Grip was astonishing as was the amount of water they were shifting and we were doing respectable lap times whilst others were spinning. Not that we could see much mind! No good on a damp circuit though as they heat up very quickly and break up.

I rented a Tiger Avon for the day at Cadwell, it was <10 degrees and rained all day. The car had an aero screen and no doors, full cage. R888 tyres. It was horrendous.

I took this pic of a few buddies cars and my own at an airfield day a few years back, I think it epitomises lightweight cars and rain wink

9/10ths of wet driving is about the driver rather than the car.

It takes some time to build up some understanding of what any car is doing in the wet but a se7en shouldn't be any worse than a tin-top (worth getting a fog-proof visor and bikers waterproof though!).
