H&R Slider Chassis Width Measurements

[goosenapper]

I am considering fitting an H&R slider chassis under a 1/24 scale '82 Buick Regal model body, but was wondering what sized wheels would best fit.

The H&R wheelbase is easy to find online (92mm to 123mm) however no one seems to mention minimum track width. I understand that there are plastic spacers which may be removed, but at some point the chassis is going to get in the way of reducing the track. What are the minimum widths that the chassis can accommodate in both the front and rear? Additionally, what are the different minimum track widths when using the 27x12 and the 27x18 on the rear axle?

Here are the rough maximum track widths that my model body can allow:
front: 73mm
rear: 76mm

With a wheelbase of 115mm, the chassis will certainly work length-wise, but I am wondering whether or not to go with the 27x12 or 27x18 rear wheels. My budget is not unlimited, so I can not afford to order both sizes and see what works best. I'm hoping that someone out there has run in to the same situation and may heave the track measurements handy. Thanks.

Hi Goose,

The front part of the chassis measures approx 32mm and the rear of the chassis 33.6mm.
The set of 12mm wheels (HRW2712R) measures about 11mm for tire, but the total width is 15.5mm for the axle boss with the grub screw.
The 18mm rear wheels are 18mm wide across the tire, the wheel being 17mm wide. These is a very slight protrusion of the axle boss on the back of the wheel, maybe 0.5mm or less.

With no spacers on the rear axle I measure approx 72.5mm - that would be the minimum.
I have similar on the front but I have a pair of 5mm spacers on the axle.

Those are exactly the measurements that I was looking for! Thank you very much for taking the time to measure your chassis and post the results. My questions are answered now and it's on to the build. :D

Thanks again!
