  1. 5th in pro out of the final top 16 then top 8 cars, which is not bad at all, in a single event.

     

    overall position having just looked on the BDC site is 17th out of 30 drivers, which again is not bad

     

    jon has not been able to do every event due to event clashes between BDC and JDM, and other financial issues, his wedding etc etc

     

    but im not sure what the format is for JDM allstars

     

    to be honest, ive had little to do with Jons season, kinda preoccupied with other things....but for a season where he hasnt managed every event, and driving someone elses car, hes done better than other that did every event, with there own car!!

  2. Personally i would only be interested in tuning the front bars.... In a few cases like the 5 i would remove the rear bar and throw it away.

     

     

    really...

     

    quite the opposite id say, on a rear wheel drive car you need to give the rear some control, by removing the rear completely and relying on the front only, you would increase understeer.

     

    a soft or OEM front bar, and harder than OEM rear will increase oversteer, you need to find the balance hence the use of the bars correct for the application.

     

    for example, on my original blue car, due to the lack of outright power, i removed the front bar, and fitted a 215% rear bar, this gave me the controlled oversteer i needed

     

    on the white car, i had to increase the front bar, but decrease the rear bar, as it had a natural tendency to oversteer, i had to dial back in some control

  3. the rear would benefit more from an adjustable bar, and generally, manufacturers if offering adjustable bars, offer them only for the rear.

     

    only a few offer adjustable fronts as well

     

    which bar you use and in which application, to either increase or decrease under, or oversteer, depends on many factors.

     

    some of which include

     

    is the car front/rear wheel drive

     

    and most importantly, what is the car used for!!

  4. bump on both wheels at the same time, ....i see what your saying, but under equal 0 load, there is nothing acting upon the bar, other than to move it in its static mount on the chassis, therefore..... there is no requirement for the roll bar to act, its function is to reduce body roll only, which of course you know

     

    hence why its is static on the chassis, but linked to each suspension

     

    the adjustment is determined by the manufacture of the bars....you would hope with some degree of testing

     

    some are set so it is +% of stiffness on each setting, or as with some bars, a -% std setting and a +% setting.

     

    tas stated the amount, is determined by the manufacturer of the bars

     

    for example the settings for some of the multi setting bars on the is200/300 are as follows

     

    Hotchkis

    32mm Front Hollow 2 way adjustable +56%, +61%

    19mm Rear Hollow 2 way adjustable +144%, +227%

     

     

    Largus

    Front 35.1mm - 140% Stiffer

    Rear 27.5mm - 220% Stiffer

     

    the Do-LUCK and TTE bars are 3 setting adjustable but dont have my paperwork to hand to say what the settings are

     

    the plus settings are % over the standard resistance OEM bars
