5KinKP60 Regular Location: Finland Registered: June 2002	Re: removing Ackerman Steering Sun, 08 September 2002 18:42 I posted this Q at club4AG as well. Here is one response I got on that site. --- --- In one of the little details that make a big difference, but you generally don't see very many people playing with it. It's not just circle track and sprinters that deal with ackerman; any well-built race car will do it too. You want to straighten out the steering arms so that a line drawn from the centre of the bottom ball joint is parallel to the centre line of the car. You will have to fabricate the new steering arms yourself. I've done this on a couple TE27s and it makes a huge difference. --- --- In a private email he confirmed that it made car "more predictable" in track environment. I vaguely recall Mr. Carroll to have said that reducing Ackerman pays off in race track work. I think we (Jonny especially) have done a good job so far. Looks like no matter on what surface you race (or just drive fast for no reason), reducing Ackerman is beneficial. It's more time and sweat consuming to verify further just how much we should run Ackerman. Technique involved. I've read on a domestic rally people's forum that what guys do is to heat up steering arms with a torch - and just simply bend them to new shape. My personal instinct tells me cast iron isn't really happy getting treated like that. Does anyone on this forum have info on needed after treatment in such case? I wouldn't be surprised to hear that baking in a 300 degree oven for three days would do good. (That's how around the world cast iron is heat treated to rid metal off internal stresses, so it would not crack that easily. Other way is to leave it be after casting for few years. -Related info- That's why Brembo brake discs cost so much, they are not heat treated, they're left alone for few years before final machining takes place.) I hope this thread does not die off before more information is recovered around this subject. - A. [Updated on: Sun, 08 September 2002 18:43] [Report message to a moderator]
