Hi James, thought I might show you what I did on two of my Vega Funny Cars. Maybe this will help with your ride height correction. I think the Revell Funny Cars are 1/24th scale, not 1/25th as advertised. I don't care for the two piece silks that come with the original kit, so on the Barry Setzer Vega, I shortened the rear wheel openings about a quarter of an inch, and used slicks from an MPC funny car. On the Pisano& Matsubara Vega I left the wheel openings as Revell had them but raised the rear axle mount points by removing the mounts from the frame rails and reattaching them as high as they would go without having to modify the frame rails, and then I used tires and slicks from current Monogram style funny car kits. These slicks are much bigger than Revells, and to me, look much more realistic. Hope this helps!
