I'm havin trouble uploading pics. Maybe I've reached my attachment limit. I'm lazy anyway so further updates will be posted here: http://www.nissansilvia.com/forums/index.p...howtopic=431244 Feel free to continue commenting here tho.

If i am, it's not intentional. How do u set up STEERING to give an oversteer tendency? Drift cars generally have a slight understeer tendency. It's a side-effect of softening the rear end for more traction. You have to get ur entry right and throw it into the corner. It's harder to drift but well worth it. This is what we're aiming for and why it'll run a bigger front swaybar but stock rear swaybar.

Small update. Did half a day's work today. Had no 3mm plate left to finish the strut tops tho.

Nigel on nissansilvia cuts and welds S14 and S15 knuckles to whatever specs u want. Lloyd's just waiting to sell another car and he'll be able to get the ball rolling with all this stuff.

Yep pretty much.

Nope keeping S13 arms standard length. Moving strut tower tops outwards by about 50mm and using about 15x8.5 +25 wheels (usually people use about -10 or so offset at the front)

Moving the inner pivots straight up then moving the outer tie rod pivots straight down by the same amount will have EXACTLY the same bump-steer as wen u started. Moving the outer lca pivots down and moving the inner pivots up will both throw out bump steer and need correcting either way. Sounds like you've been lucky enough to mainly deal with toyota setups. Roll centre adjustment is very easy because the spindles are separate from the knuckles so all u need is a big spacer between and ur set. Bump steer unchanged.

Silvia front stuff for a number of reasons including parts availability, easy 5 stud, easy big brakes, readily available modified knuckles to our specs, wider track whilst still retaining a low scrub radius which makes steering feel much better, power steering etc. etc. Keen to hear about the geometry problems you mentioned. Still in early stages of build so open to suggestions. If 2 of those problems are bump-steer and ackerman, that will be sorted with custom knuckles. Will be running modified knuckles to increase lock, reduce turns to lock, reduce ackerman and correct bump-steer. The inner and outer tie rod pivots will be parallel to the inner and outer LCA pivots for the least amount of bump-steer possible. The inner pivots definately need to come up to raise the front roll centre which goes very low when lowering. The rear doesn't do this so un-corrected, the balance of the car is very over-steery. Yep handbrake will be sweet as-is. Maybe thicker cables.
