what is an 'early' 3.4 996?
Discussion
There was some fear years ago about fitting bigger wheels and / or tyres to early Boxster due to strength in shell woes. I'm not sure I buy into that. The later 996 came with the 285 but is it's shell stronger - no idea. Personally I think bigger isn't better and I'm going the other way. I might try thinner on the back of mine. I'm tempted to try 4 fronts and see how it feels. Only reason I've not done it yet is not sure what to do about pressures if I do. I have a pair of lightly used MPS4 in 265 35 18 sat in my storage bin if anyone wants.

I ran a square setup on my 986S on trackdays and it worked well not sure a 996 is suitable for that though.ATM said:
Plenty complaints on internet about understeer on a 996. Fatter rears will not help this.
I can't say that mine has felt understeery at all. Mind you I do usually run it with a mostly full tank of fuel to put some weight over the nose, that's something from my VW Beetle days thoughanonymous said:

Muchos different pressures for 17 and 18.17 book says 36 36 - I am now on 31 31
18 book says 36 44 - I ran 28 32
Only reason I can think of is wider 18 rear tyre needing more pressure to stop deforming. Total guess work. Although front 17 tyre narrower and yet not less pressure.
Doubt you’d feel much difference between a 265 and a 285. Mines on 265’s, and it’s almost impossible to unstick the rear in the dry unless you deliberately try to unsettle it on the way in... and the speed you need to do it isn’t really safe for public roads. Bit different in the wet, but even then the rear traction is pretty much unbreakable unless you’re really trying.
As for understeer... yes they will understeer, but nothing that trail braking on the way in, or a lift mid corner won’t sort out. Once you get them turned in you can load them up really hard and they are pretty neutral after that.

The problem for me is I'm half the driver or push half as much as this. I have never got the back out of shape ever. I've given up trying. I do enjoy the feeling of a lift entering a corner but that was when I lived in the wilds. Now I'm just pottering around 30 limit congested roads so the enjoyment for me is the feel of the gear shifts, the lovely feedback and the smug feeling that I appear to be a car enthusiast to the average people looking at me.

Talking of tyre sizes whenever I put in my reg number in a tyre search the rears come up as 285/35 18 yet the tyres on it are 265/35 18. As my Continentals are pushing 7 years in age I’m thinking of changing them even though there’s plenty of tread left. Toying with either Goodyear F1 assymetrical(got them on my WRX and they’re very good) or pushing the boat out and getting Michelin PS4s.

After a rather nasty skiing injury I’m back home from hospital & I need to a least start my 2000 C4, it’s been 19 days since it last ran.
Unfortunately it’s going to be months before I can drive it so any tips on what I should do above start & move it down drive & back
Pump up the tyres a bit and put it on a battery conditioner. Don't start it. Leave the handbrake off. Unfortunately it’s going to be months before I can drive it so any tips on what I should do above start & move it down drive & back

I'm on 265 rear and albeit i have a very safe alignment spec at the moment the rear is nowhere near giving out whereas i can get the front to slide when loaded up. I need more front camber and maybe a little less rear toe in to make the car more balancedAs for understeer... yes they will understeer, but nothing that trail braking on the way in, or a lift mid corner won’t sort out.

I've had PS4's on mine for the last year, and I love them... I've run PS2's, P Zeros and Contis in the past and would take the PS4's over any of them.skinny said:

Mine's X74 alignment, so nothing particularly aggressive (bit less toe, bit more camber, but not enough to make it twitchy). I do have a much thicker rear ARB on mine (adjustable H&R) and an M030 front bar, and that made it feel more 'pointy'. Other than that, I think it's down to how you drive them - you simply have to keep the weight over the front on corner entry. It's not about having the rear moving around to swing the car in (that would be a bit daft on public roads), but about shifting what grip there is between the front and the back using the weight.
