Tire Size Options for Spyder
#31
Did some of us get n0 and some got n1 on the Spyders? I need to check. Fwiw, I don't like the feel I get from the tires, but as I'm still on first set I don't know if it's the electric steering which feels so dead, or tires. They also feet a bit slippery when I'm on it in the turns. Looking forward to trying something different

Tire rack has not done comparison testing of the N1 yet.
I do not think the steering is "dead", it is not as direct as in the 987.2 Spyder but it's quicker, and that plus the improved chassis/suspension bits makes overall handling better to me.

I think the steering feel will improve if switched to better rubber such as Pilot Super Sport or Cup 2. Few months ago, I switched to Super Sport on the S2000. The steering feel immediately improved. It is a lot meatier and with more feel. In fact, the steering feels better than Spyder's; but, lot slower. Spyder's steering is pretty quick. But, I prefer meatier feel over quickness.

I got N1. It is still numb! I read that the GT4's feel is better, which came from GT3. Perhaps technically savvy members could explain why Porsche didn't offer GT4's setup, instead of sticking the rack from 991 Turbo.

There is a test on Tire Rack now that includes MPSS and the Pirelli PZ4, but not the N1 version as the car was a BMW.

I must be an outlier. I think the Spyder's steering is dialed in, even when comparing to hydaulic units from my "pure" cars of today and years past. The fact that it is electric makes it that much more impressive.

I must say the steering feel for me has changed as in I got more used to it. I only have 2200 miles on it since I got it in March. But I am liking the steering more and more. It's pinpoint accurate and really fast and twitchy just how I like it. Now if I go back to my M3 I am sure I will find it dull and slow despite having more road feel in it. I think what Porsche have done is impressive and give enough info through the wheel and nothing more. And now it's an exercise for the driver to adapt to it and make of it what they will. Also psi set to 30 on the Pirellis helped I think. Sure my mpg dropped a bit meh!

This is correct for the GT4, but the Spyder steering is actually 'plucked' from the 911 Turbo.

Interesting, thanks for the input.
So the front diameters are as follows:
235/35 OEM: 26.4"
245/35: 26.8"
If I were to change the fronts to 245/35 and the rears to 285/35, they increase in diameter by roughly the same percentage.
Another, cheaper option is to leave the front as-is and address the rears only with wider PZeros.

Hi,
A Spyder driver from Germany put the same tires as the GT4 on its standard Spyder wheels and it seems worked out very well.
Tire is MPSS and formats are:
- Rear: MPSS 295/30/20
- Front: MPSS 245/35/20
He posted some pics and it works without any spacers, as I understood.

no...if the front stays the same and rear width is wider understeer will increase.
Now honestly by how much, and will it be noticeable for street driving? Not much and maybe no difference. For me at least, less understeer then from the factory (to a point) is better, so anything done that increases it I avoid.
