Assuming all the other factors stay same, including tread pattern, engine power, is this always so? Also does it always result in faster acceleration? And by wider rear tyres, I mean the sorts of sizes that are readily available in places like KwikFit, and Blackcircles ets, not F1 tyres... What are the downsides of having wider rear tyres in real world situations? - Apart from the price of replacement! Thanks (Sorry I know this subject has been touched on before here)

Exactly what i was thinking I feel the spacers have changed the scrub radius meaning the previous calibration is redundant.... Im sure your right Tony. But to answer you I have never pushed the car to its limits in this way before ever - only done it since the spacers were fitted. But given the new spacers I think the "limits" have changed a bit.

thats good advice.. and yes its deceptive.

It certainly feels like it was on the limit of grip, I took it at about 35 mph, but it feel like if I would have pushed it more that the front tyres would have skidded in the direction the car was pointing, rather than the back-end stepping out. BTW The wheel rub on the 25mm spacers all round was solved by the rear inner arches being cut.

Is this what is happening when i take a corner too fast in my skyline? The weight *seems* to be mostly going on the passenger front wheel but how can that be if its a right corner? Are my senses deluded? Tony u my know the corner I take... its round the back of quick fit not to far from STS - that two lane bendy 40mph road just before the turn off to the halfords retail park. Enlighten me.

thats a good idea tony, dipping the camber.. but what would it do to the handling. id have to see you after i get the smaller spacers hubs. Carl

not only did i feel a difference (probably subjective) I heard one too. the sound of the damn tyres fouling the rear arches on turns. bumps, and harsh acceleration. Solution: exchanging the 25mm hubcentrics for 20mm ones.

"Calibration?" hard to say on the fly... I would need to retain the projected inclination near to zero on your car.... (0 scrub radius) this thread may help.... http://www.wheels-inmotion.co.uk/forum/ind...p?showtopic=561 Sounds interesting even though I cant understand the details. I should be getting the car back tomorrow, with or without spacers. If spacers are fitted, I woder if i will *feel* a difference.

talk to me... too much?

Yes Tony, good you are local. looks like im going for 25mm spacers all round.

It would be welcome Tony.

ahh i see what you mean. I reckon I will put the spacers on anyway. If there is wheel bearing failure, then I will deal with that as and when. Thanks for the heads up about it though. The bodykit screams "put spacers on me!" on a daily basis.

No intention to race the car. Just local high street use, shopping etc if the hubcentric spacers (aluminium and TUV approved) are going to cause safety issues I'd rather do without them. Would the safety risk issues increase with the spacer width... eg 15mm vs 25 mm? Assuming all the risks regarding bearings and studs are resolved "we" would have major issues with the new tyre contact patch. By design off-set allows the tyre contact patch to fall within the front steer axis (scrub radius) and the rear needs to transport traction efficiently to belay pneumatic saturation during yaw commands. The type of mod suggested needs careful consideration. Yes... It would seem like letting the tyres naturally wear down, and then purchasing wheels with the correct offset for the model would be a better idea from a safety point of view, is that right? Could I just then ask a wheel supplier for say 18 inch wheels with my particular offset I need?

so if I understand then the procedure recomended is to 1)find geometric attiditude at chassis, then 2) install desired spacers. then repeat the step 1. or what am I missing Tony?
