RE: 1600 handling question - understeer & bounce

[Jeff Oldham]

Hey Errol,   the suspension on my datsun 1600 sits high at the front just like the white car on your web site. the guy that i bought the car used to rally a 1600 so maybe he set this one up similiar ? or maybe he just had those bits left over and chucked em in ? suspension seems a little hard for a street car, but is certainly too soft for a race car and i will need to reduce body roll as well   i personally think that my car sits too high at the front.....for tarmac anyway.   ohh well hopefully next year i will have some cash to spend on some better bits n pieces.     ta Jeff     thats interesting info, my first reaction was to lower the tyre pressure to try to get more traction.....sounds like they need to be firmer.   thanks for ur help.....im running at mt cotton on sunday   cheers jeff The problem you describe is more likely to be tread squirm from under inflation and also soft spring rates. A strut brace will not solve this. A steering box brace will help make it feel a bit more positive. Check the sidewalls of the tyres and see where the scrub marks are coming to. They should not be off the treaded area of the tyre by more than 5-10 mm depending on tyre sizes and profile used.   The above is a bit general and hard to help with as there are so many variable such as suspension condition etc.   Cheers, Feral Errol Get Serious  http://www.datrats.com.au/ -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Rob P Sent: Tuesday, December 02, 2003 4:10 PM To: [EMAIL PROTECTED] Subject: Re: 1600 handling question - understeer & bounce Sounds like you might benefit from a steering box brace - see Maddat or Datsport. A strut brace will make a noticeable difference to chassis rigidity if that is the problem, mine did even on the street - see Cam Mckinnon. Other things to consider are suspension settings. I think it's been said that a harder rear setting gives a bit more oversteer?? anyone? If the front is bouncing up and down perhaps the dampers are not working as well as they should either. Don't quote me I'm just regurgitating stuff other people have posted :-). Errol would know better.   Rob P     ----- Original Message ----- From: Jeff Oldham To: [EMAIL PROTECTED] Sent: Tuesday, December 02, 2003 8:56 AM Subject: 1600 handling question - understeer & bounce Hi troops,     i have a handling question with my 1600 i have understeer that i am trying to equalise also the car feels a bit like the front bounces when it corners and the grip seems to come & go....i can feel it in the steering wheel   this is hard cornering at speed on a race track, not street driving.   will a strutt brace help with these issues ?     thanks Jeff --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ ---------------------------------------------------------------------
