Reading these prices

Starting prices aren't always comparable. Some include suspension, steering and brakes; some are a bare frame or front clip and the rest is extra. Check the Front and Rear columns and each product's notes before comparing totals. "Price on request" means the builder quotes each build. Confirm with the builder before you order, and send corrections through our contact page.

Upgrade the original chassis

How it's built: Body-on-frame perimeter ladder frame; fiberglass body over a steel birdcage
Front suspension: SLA A-arms with ball joints and coil springs; Saginaw recirculating-ball steering, optional linkage-assist power
Rear suspension: Independent: frame-mounted differential, transverse multi-leaf spring, half-shafts as upper links, trailing arms and strut rods
Weak spots: Soft trailing-arm and strut-rod bushings let rear toe and camber change under load. The heavy multi-leaf transverse spring, frame flex and slow linkage-assist steering limit precision.
