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

For handeling the wider the better (within reason).

should get the ride hight you want, and then pack them out as far as posible.

Datsun 1200 stock wheels are 30mm offset.

Datsun 1200 has the same track width 1240mm front 1245mm back. With 4" wheels and +30mm offset, wider wheels will be quite different.

Wider tire advantage probably outweigh any disadvantage from the changed track, roll center and bumpsteer changes. For a street car, at least.

My coupe is not unlike many SCCA 1200 race cars in that the front track is about 20mm more than the back. The car will turn in very nicely, naturally, but the reason for this is the 280ZX struts and control arms mounted on my 1200 have a wider track. This isn't something I would go out of my way to do.
My recommendation to you is get a copy of Carroll Smith's "Engineer to Win" & "Prepare to Win" , also Fred Puhn's "How to make you're car handle" or look at the C Sedan prep manual on this site. For a street car an A14 or A12 with GX Spec Cam, Weber DGV, Headers, 2 inch exhaust paired with anti roll bars, some decent dampers and a set of 175 or 185/60 13's and better brake calipers or at least pads would make a fun little street car.

Thanks for all this info, will have a look at C sedan prep and check the track against 1240 and 1245mm.......

Is the C sedan prep the Datsun 1200 competion suspension in the downloads.........
