cool thanks, so the lighter the unsprung weight the better the road holding?

Hiya, I have 15x6.5 on my 1200 with 195/45, +40 off set, with b310 struts. They need at least a 8mm spacer but heaps of room for turning about 30mm at back, I have also had to fit longer wheel studs. I am planning to put more negative camber witch will help get them under the gards but I will have to lip them also

That makes heaps of sense, but thing I don,t understand is unsprung weight, what it is and how dose this affect it....

I,m thinking about doing this to my car.

I,m having to use spacers to fit my wheels on my 1200 sedan because they are +40 offset, but then I had a brain wave last night about the diff in track from front to back. Front struts and bottom arms are B310 and wheels will fit on the back ok without spacers.
This combo give me about an extra 20/30mm track on the front and reduced track on the back by about 20mm, makes diff of 40/50mm front to back.
The reason I thought it may be a good idea is because if you look at F1 cars( and I know its hard to compair a humbel F1 car to the mighty 1200), but they have heaps of extra track on the front. It will also make easy to lower the car more as the back wheels will go right up under the gards without rubbing.....Any thoughts if this setup will be better for cornering or should I do it just to get the car lower.......Thanks Jason

Yeah I,m sure a ca or sr will have heaps of h/p and be great to drive, but it depends on what your trying to do with your car. Yes my car is an a series, it will have better weight dispersment and will corner better than a ca powered car and therefor will be faster.

Yes it seams a shame to add all the weight back on after removing it, will add more h/p and look out for lighter wheels..........

Looks like I,m going to have to add more h/p.....

Yeah guess that is the price you pay, I brought them because I thought they would look good on my car. I did,nt weigh the tyres befor they were fitted but I would think tyres would weigh more than they did in the eary 70s. The guy at the tyre shop said that a lot of steel goes into them now.
It just seams a bit dissapointing after taking off 25.5kg to put it back on to have a flash set of wheels...

I think the seats are heavy, also carpet weights a bit also but its a road car and don,t really want to go full race trim. The standard wheel and tyre weighed 10kg and the new wheel and tyre weighed 16kg, so thats 6kg diff x 4 wheels = 24kg.
Also I know cyclists go on and on about the weight of the wheels on bikes and whos got the lightest wheels, and talk about rolling weight etc
