You asked so……..
Finally, after putting these through the wringer and some real world testing in various conditions we are proud to release these for general sale

billet steel rear 13b and 12a counterweights.

For those that need to know…..
☑️ These are 200+ g heavier than stock and also come un drilled like the random aftermarket and Mazda rear counterweights, you builders who know about balancing will know why…. Mallory just went up to nearly £500 for a foot 👀
☑️ taper will not stretch like other aftermarket weights resulting in loss of endplay and reduced keyway sheer for the drag bois.
☑️ comes with 10.9 or optional arp hardware
☑️ tool steel “snug” keyways also available

PLEASE NOTE: you will need your assembly rebalanced to fit these, like you should fitting any counterweight to a manual assembly

The first 10 are already sold and have very limited number left, next batch will be bigger quantities.
Big love, Reg

And here’s the exact reason we made these all those years ago. Not wire cut rx8 inserts like others are selling. made from scratch and heat treated right here in the uk, tired of losing your rubber inserts, dont want to run solids, use these

Edit, picture of corner seal travel found off the internet and seems it belongs to the biggest cry baby in the world with anger management issues so its been deleted

Another large run of 1/2” studding on today (thanks for your patience). We interpolate to any tolerance of clearance you may require for different builders and different combinations on our centreless ground studs using our oversize 1pc dowells for a tight location all the way through.

Proven worldwide in 800hp street cars, 50psi on cast iron Mazda plates and 75+psi on billet motors. 🫡
