These extended lower ball joints made by Bauer Limited Production allow you to increase negative camber by -2°. So whatever maximum negative you have now, add 2 more degrees. Most high performance and race tires want between -2.5 and -4.0° for maximum cornering grip.
Supplied as a pair and direct replacement for the OEM front lower ball joints.
Suits all Mazda MX5 NA & NB 89-04
