Introducing the latest innovation in competition suspension products for your Porsche 986/997/986/987/981 & 991 (not GT4 or 991 GT3). Designed and manufactured by the ERP Suspension Engineering, this unique lower control arm design is far superior in reliability, quality, and performance to anything else available on the market today.
These bad boys are more than just a machined replica of the factory arms. The ERP Pro-Series lower control arms are fabricated from aerospace quality 4130 chromoly steel, tig welded together, and then heat treated and finished with protective coating of electro-less nickel. Camber, caster and wheel base can all be adjusted quickly and precisely with a simple turnbuckle link design. No shims to add or remove. In addition, this kit includes precision adjustable diagonal links for fine tuning caster and adjusting wheel base. All pivot points, at the chassis connection consists of oversized precision grade Teflon lined rod ends. The ball joint also consists of oversized precision grade Teflon lined monoball bushings. The diagonal link to the chassis connection point uses the 997 RSR design which allows it to be raised or lowered to reduce squat and dive during acceleration. For safety, the problematic 12mm ball joint design, used on both OEM and aftermarket arms, has been completely redesigned for a full proof, significantly stronger, and more reliable design that you can count on. To top off this no compromise design the center geometry can also be adjusted to correct for lower ride heights. All kits come complete for one axle with all the parts and hardware necessary for a bolt in direct replacement for the OEM arms.
