I will be upping the power of my z soon, what is the best tyre (17") to achieve substantial grip.

 

Thoughts

I started at 32 psi and worked my way down to 28 psi . I had the dampers on full then backed them of at the rear 50% hoping a stiffer front would dial in some understeer .... nope .

 

Defo weakest link is the tyres

I second what Chris said, pressures are very important, particularly in the wet. Then suspension set up can make a huge difference, you want some compliance in the car.

 

I like vredestien vorties.

 

Avoid yokohamas.

 

Toyos are good.

 

Thinking Michelin ps2 or ps4.

 

 

Had toyos on my s2000 and they were very good in the dry but not amazing in the wet . I live in Wales, it's wet most of the time here lol .

Have you corrected rear camber since changing ride height?

No I haven't had it done professionally, but the car sits better since I lowered it , after fitting all the suspension bits the car sat a little higher than before and the rear looked like they had a tiny bit of positive camber and now they look spot on .

Also the car feels planted and not skitish at all .

The pic is before I lowered it , see the rear has a touch of positive.

I know what your thinking Chris , too much negative camber and less contact patch.

 

I did plan on having it setup at orchard garage in newport who did the geo on my s2000 years ago, but I ran out of time .

I would start with having a full alignment done on a hunter or equivalent (by someone who knows how to use it).

 

I have PS3 on the rear and really rate them. I never track the car though and it doesnt come out of the garage if its wet.

 

The odd time i have been caught out in the wet they perform very well (im well under 450hp though).

 

I had someone following once in the wet and they had to drop right back due to the spray from the rear tyres which proves they displace water very well.

Rex, I really like your car by the way, I think it sits really well and is a handsome thing :thumbup1:

 

How I learned about tyres. One dark wet night me and my cousin went out in my MX5 and messed about with the tyre pressures. We did about a tank of fuel doing this across hours of driving. We had 30psi all round, as well as 40 and 20 all round. Then 40 front with 20 rear and the opposite. We found that higher pressures gave more grip in the wet. Ultimately something like 28 front vs 32 rear in the case of the Mx5. This is a very valuable experiment if you dare to and have the time.

 

I'm going to do it again in the zed because I'm starting to forget what we learned. But high pressures worked better.

 

I have my car really dialled in, but it will always slide about if you don't stop it from doing it.

As already said its vital to have suspension set up correctly BEFORE thinking about what make of tyre.

And certainly BEFORE you go on track:scared:

As Chris already said a Hunter Hawkeye is one of the best.

It does of course need a skilled operator not just someone who looks on the wall chart for settings.

Std Nissan settings are a great starting place... then alter the settings in the light of your results on track.

Mine are all somewhere on another thread.......

They work for me but I may be moving to a different tyre in 2018 so possibly a little change might be needed.

Im sure you already know but remember to set your ride height first as changing that messes all the other setting up.
