Dave’s R100 has been back in the workshop for some winter rear-end upgrades, with one clear goal in mind… improving the 60-foot times and making the car more consistent off the line.
To help achieve that, the boys have fitted a set of custom Penske 8300 double adjustable rear shocks, built specifically for the R100 chassis setup. While the rear end was apart, the old anti-roll bar setup was removed and replaced with a CJ Racecars “Big Johnson” anti-roll bar kit.
As anyone who has worked on an R100 knows, space is extremely limited, so Todd had to get creative to make the new ARB work effectively while still allowing room for future upgrades and servicing access.
With the rear end removed, Todd went about removing the old chassis support bars before fabricating and fitting a new rear cross brace setup. The chassis bars were then repositioned to allow fitment of a Tim McAmis rear driveshaft enclosure for added safety.
While everything was apart, Todd also fabricated a custom transmission belly pan designed to help prevent transmission fluid from making its way onto the rear tyres in the event of a component failure.
To finish off the rear-end upgrades, Mick wired in Dave’s rear shock sensors to complete the package.
We’re looking forward to seeing what improvements these changes bring once the track reopens following the new surface upgrade.
Stay tuned for more updates next season 👌
