    Yeah but

    Wouldn't that depend also on wheel / tyre type and width etc etc would all come into play?

    You know what the issue with low suspension is ???

    You havent just reduced the roll centre.

    You have perverted the bump steer and rear toe angles to the point where it just wont handle as well.

    Why do you think JP has changed the arm geometry on the Slot car? Well I will tell you.

    As the sub farame approaches the ground. The rear control arm angles to the wheels change massively. In the stock suspension The change in angle VS spring compression is almost linear. ie: the change in toe and camber angle as the suspension goes up and down is almost the same.

    As the car is lowered using the spring locks. You pervert the linearity of this toe and camber change. IE: 25mm up may be + 1/2 a degree camber and/or tow. While 25mm down only changes it by -1/4 of a degree.

    In other words You are screwing your bump steer performance up.

    Have a look at the photos of JP's rear suspension cradle in that thread last week. You will see he actually redrilled the lower arm mounting point in the rear subframe and inch higher and remounted the lower arm to fix this.

    There is only one way to lower the car and keep the correct geometry and that is to use lower arm links like the Ikea links that use spacers fitted to the lower ball joints. This keeps the suspension arm geometry the same as stock.

    SO feel free the change WTF you want and lower the car to the ground. What do I care. But by doing it KNOW YOU ARE SCREWING IT'S HANDLING UP.

    If you reckon that it will handle anywhere near as good as at stock height you are in for a rude shock. UNLESS it is lowered correctly.

    P.S. having slicks doesnt compensate for piss poor suspension setup.

    The caster, camber and toe settings front and rear are completely different for slicks and road tyres.

    dear sir tek, (my love)

    i am not disagreeing with anything you put in this post whatsoever. but you cannot come on the forum and point the finger at me as being totally wrong about the way i run my car.

    when i had my car at sandown it impressed me very much. even though the calculations may be way out of whack its fine by me because it was flying around sandown like nothing. at times i was overpowering the track but it was fine. i had a blast. and thats what matters.

    but i will not raise the car. i love it just the way it is i love the way it handles i just had a new wheel alignment by your friend at ttf. and its way way way better now since last time. no harm done we just both have different views on how we want our cars to be. im not looking for a racecar and what i have is more than enough.

    i still love ya peace out im going out to chaps for a coffee bro's .......

    CHAPS LAPS! Hektik!

    Sorry.. I agree though, have the car at the height you want, of course Nissan did things for a reason, so whenever you mod it, you're changing specs.

    For me, I want a clean, immaculate and original zed (will buy another one later to make 1,000,000rwkw) so I'm going all stock :D. That and the next time Ugame says that a stock 350z is about as fast as a stock 300zx TT, I can prove him wrong! :)

    Sweetie,

    The reason I am giving you heaps, Your car didnt perform against the Falcon. Despite him running street tyres and sticking his C@ck up you.

    Now there is a reason he screwed you. Your suspension setup let you down. I am giving you the reasons why you got c@cked.

    Slicks or no Slicks doesnt matter. He didnt have em either.

    If you want your car to hook up better. The reasons where in the previous posts.

    If you like it how it is, I am good with it. Its not my car :eek:

    BUT you have to be prepared to have your ass handed to you each time you go to the drags or the track, by cars that have way less power but better suspension setups.

    I would have to do something about that as it would piss me off.

    This is my whole point. Best power for the street is a silly concept because there is way more to street driving that a drag strip.

    There is a better solution with less compromise for street, track or drags than you have now.

    Lastly, you are not the only one who is under the misaprehension that lower is better. You where just a good example.

    If your ass wasnt so much lower to the ground that you need a ladder to climb in at stock height. I wouldnt let up on you :p

    Supprising as it my be...... there is a huge setup diferace between street and strip as there is for the track.

    I can honestly say that a good suspension change to a street car thats specifically for the strip WILL cut a cars time by as much 1sec
    :eek:
    Add in some tyre changes and the setup to suit the strips "enviroment" at the time rather than just running the 'basic' setup & and additional .5sec can be had...... 1.5secs faster over 400mteres may not seem like much, but in track terms lets do the maths..... Say the track is 2km long... if your 1.5secs faster over 400metres then what if it could equal 7.5sec faster over the 2Km track !
    7.5secs is a long way between cars when at racing speeds

    Ok so its not quite the same, but you get the idea.... drags require alot of setup changes to get the best from any car and there are some big gains to be had...... with the right changes a 14 sec car can run a 12.5 pass and 90% of that gain will be in the first 60feet !!!
    My E55 Charger has run a 10.1sec pass, not bad for a street registered car, I know now that had I dropped the rear tyre pressure by 2lbs I may have run that magic 10.0sec pass, if only I knew back then....:eek:


    There's a whole science to drag racing just as there is to track racing and street use.... The 3 differning surfaces/enviroments each require 3 differing approaches to get the very best from any car.

    It might only be 400metres..... but get it right and you'll have a woody that will see the wife move back home to her parents for a month just to be safe
    :D
