This is a K's F1 racing chassis based on the Tamiya F103 chassis. This kit uses F103 wheels and body kits with a high nose. I had searched high and low to try and obtain these kits for years and finally saw not one but two listings on Ebay. One listing was a newly built kit complete listed as a Kyosho OVA car. I won this listing for $202.00 The second listing was for a NIB kit which the seller ended because the kit turned out not to be comeplete. Anyway the seller relisted the box and parts including chassis plates, shocks, ball diff, etc for $100..00, so basically for $350 including shipping, I got a complete newly built kit and a box of spares. I was very happy!. The kit is all aluminum and carbon fiber. It features belt driven ball diff, push rod inboard suspension, arms by RPM, tie rod ends from Kyosho and rear universals. The chassis in the picture has a tamiya front wing, 3 racing rear wing and RJ ride grooved F/R wheels and tires.
