I have a Super Stalker that we autocross pretty often, Glen gave me an opportunity to take a few runs in their Mspec V8 Stalker. I really didn't think it would be that much different...... I was very wrong! The new suspension coupled with the V8 and other refinements (steering etc) made a HUGE difference. That car simply did anything I asked it to do, effortlessly and VERY fast.
My Super Stalker is no slouch, but I plan to have an Stalker Mspec or AXR in the garage one of these years!
