Short track ovals: Wilwood announces new GM D154 Metric Caliper

Alfie Bilk, March 1, 2015 These ultra-strong forged calipers are fully detail machined and stress-analysis tested. They provide the lightest overall weight with the highest resistance to deflection – even when compared to much heavier and bulky cast aluminum parts, bar none. The calipers feature an anodized finish, with low-heat conduction stainless steel pistons and positive retraction bore seals. Fluid inlets have been relocated to the center of the piston bore to eliminate any possible interference with the slide pins. Bleed ports at both ends accommodate left, right, front, or rear position mounting. Available with 2.00in or 2.50in pistons, Wilwood’s new high-end caliper costs only $112.20   Wilwood Partners with JJ Furillo of Ultimate Performance to Enhance Support Wilwood Disc Brakes has partnered with Ultimate Performance, a North Carolina-based suspension tuning and performance product supplier.

Mahle Motorsports Introduces Sportsman Drag Series PowerPak pistons for Chevrolet big-blocks

Fletcher, NC: Mahle Motorsports, a division of Mahle the world’s largest piston manufacturer, has introduced a new Elite Sportsman drag racing piston series for popular aftermarket competition big-block Chevrolet cylinder heads. Using lightweight, strong, true slipper-skirt forgings, Mahle’s emphasis is on power production and durability. By necessity they pay special attention to drag race-specific stress areas, notably skirts and ring lands. The pistons also feature dual coatings. A phosphate dry-film lubricant is applied to the entire piston followed by MAHLE’s proprietary GRAFAL® coating. Grafal is introduced to the skirts to minimize drag, scuffing, and cylinder bore wear. Other important considerations include gas porting and an advanced pin bore design as well as the piston’s profile and ovality geometries. Available singly or in packs of eight, with or without rings, and in bore sizes up to 4.630in. (0.030in overbore for 632cu in), the result is a custom-style, high feature piston with off-the-shelf availability. For more information, contact, or call toll...
