Billet Aluminum Flywheel

Metal Flywheel. Rebuildable/Replaceable rubbing surface.

This light weight flywheel is more or less 10 pounds less heavy then the stock flywheel.

Billet Metal Flywheel

Light-weight Metal Billet Flywheel.

Designed for and first offered by Lindsey Racing may be the SPEC Billet metal 951 Flywheel! This brand new scallop design flywheel weighs just 7-3/4 pounds. This is the stiffest flywheel designed for the 944 Turbo. Due to it really is scallop design, it simulates a flywheel nearly 3 pounds less heavy than it actually weighs. That puts it within 1 lb from it's SPEC Aluminum Flywheel cousin.

Force Plate Upgrades

Now available from Lindsey Racing are a couple of various SPEC Aluminum Pressure dish options!

The Hybrid Aluminum Pressure Plate and Full Aluminum Pressure Dish.

Crossbreed Aluminum Pressure Dish

This Optional crossbreed Aluminum Pressure dish for use with the Stage 1 through 4 clutch kits above. It raises the clamp load with less weight then a standard metal stress dish.

So you may utilize a less aggressive disk with extra holding capacity to fulfill you requirements.

The Hyrbid Aluminum stress dish (12.2 lbs.) features a metal Cover and also a Aluminum Plate with a metal replaceable friction area.

Complete Aluminum Pressure Plate

The total Aluminum Pressure Plate (8.6 lbs) features both an Aluminum Cover and Aluminum Plate (the round disk your clutch disc trips against) with a metal replaceable friction surface.

Both of these optional Pressure Plates are rated similar in clamp load or torque keeping capability, although Comprehensive Aluminum is lighter then Hybrid and just about every other single disc unit available by about 2-1/2 pounds!

Unlike their competitors, they require just 5percent even more pedal effort than stock, releases quicker, tend to be SFI approved and therefore are both "rebuildable".

It includes 20per cent even more torque keeping capacity compared to standard SPEC metallic versions which have much more clamping power than any of SACHS kits we sell.

The following figures are from SPEC for the clamp load abilities of their clutch kits for 951. They're for a unique clutch properly broken in and with a fresh or refurbished flywheel. Temperature can lessen these figures on a Stage I or II system with natural disks. Stage III and IV kits use metallic compounds that aren't impacted by heat. This will make the clutch feel the exact same on the very first through the final lap.
