We’re going a little more sophisticated on Mike’s car so it’ll be interesting to see how it turns out!
Based on Mikko’s information I went ahead and updated the spec sheet as well as dug up the Driftworks.com Forum Build. Check it out here: Drift Camaro Z28
His post #120 in the build thread (on page 6) contains some really good pictures and commentary on his front suspension changes. I’ve copied the information I was most interested in (his words in italics) below for your information, but make sure to check out his thread!
I made new lower control arms, using oldones as base. 7cm longer per side, changed wheels from 8x17et -10 to 8×16 et 8 and tyres from 235 -> 205. Now wheels can turn in THEORY 65 degrees
Then i get rid of old steering box and started to fit rack & pinion steering, i choosed Volvo 240 aluminium core rack, they use these in rally cars here and you can get different ratios to those, I had custom made infernals to that, now 2.5 turns lock to lock, in normal tarvel distance… And added 10cm more lenght to rack, so total travel now 28cm, should be enough….?
Then modified, knucles in right lenght and angle, i made bolt on adapters to knuckles, tested movements few times with those and when it was right made jigs and welded knuckles in those, maintained to keep them symmetrical that way, now it turns that 65 degrees and basically no ackerman at any turning angle. And doesn´t go near to dead angle at full lock, few days well spent
But how to route Steering axle, front crossmember was badly in way. Get 90 degree rotating gearbox to it Pic shows also how i solves upper control arm issue, i moved those from inside of brackets in frame to outside, so those moved 60cm out which correlated lenghtening of lower arms.
And last steering mod was to fit Opel Corsa C steering colum, tilt and elecric Power steering with adjustable sensitivity.
