Front suspension member, Mazda, MX-5, NA, Reinforcement

The other day, I saw some vulnerable parts from under the body. When I actually removed it, I find it’s pretty sloppy. Welding of the engine mount is about 50% of the circumference. All manufacturers are similar, but the design section would have instructed them to be OK. In particular, MX-5 NA8C Series 2 is an model born in a storm of cost reduction. In addition,weld a reinforcing plate to the base of the lower arm. Weld all around the engine mount. First attach the bottom of the reinforcing plate and then tap it. Weld the mating part. Since the spot spacing is also rough, welded all the mating parts. The mating part with the frame was reinforced with particular attention. Rigid collar have become popular in the audio world these days, but the area around the holes is carefully　reinforced. Smooths the mating surface with the frame. It is completed by painting.

Corrosion, Mazda, MX-5, NA, NB, Side sill

This is a chronic disease due to being an open car. Side sill corrosion. A drain that drains water from the soft-top rain mall to the outside of the vehicle passes through the pillars and exits through the holes in the side sill. Since water remains in the gap due to the structure, it makes rot from the inside for a long time. Peel off the painted surface and cut out the corroded part. Treat the rusted areas inside with a rust preventive. Weld the iron plate. Sharpen the bulge and tap around to make a base for putty. Apply sheet metal putty and the base is finished. Leave it for a while to harden it. After this, polish with # 80.Move on to poly putty work.
