Porsche Alignment Camber Shims
from $8.95
$66.00
Anodized Aluminum Porsche GT3 Control Arm Shims
For Porsche GT3 And Similar Two-Piece Lower Control Arms
Precision laser-cut from 6061-T6 aluminum and anodized for durability, these shims are used to adjust camber by changing length of your Porsche OEM or similarly configured lower control arm (such as these RSS units). Thickness in millimeters is silk screened on each shim for easy sorting.
One degree of negative camber is approximately a 5mm shim.
AVAILABLE SIZES:
1 mm
3 mm
5 mm
PACKAGE SAVINGS:
Enthusiast (two of each shim) save 10%
Racer (four of each shim) save 15%
Team (eight of each shim) save 20%
These fit all two-piece Porsche lower control arms (except 991 GT3/GT3RS rear, which use a different shim shape). Shims are priced individually (other than packages). They are typically used in pairs or in multiple-shim combinations. Also fits 981 and 718 Cayman models.
CMS Performance shims are used on FRONT and REAR of any Porsche 986/987/996/997 fitted with two-piece lower control arms (commonly referred to as "GT3" control arms) and ONLY FRONT of 991s with two-piece lower control arms.

Silver Rocket Custom Porsche Motorsport Front Strut Tower Reinforcement Plates

Silver Rocket Customized Porsche Motorsport Strut Tower Plates
Applications:
Porsche 718 (all models)
Porsche 981 (all models)
The Porsche front strut mount is uniform across all 981 and 718 model variants as part of the aluminum body structure. For GT and RS sub-models, which are frequently used on track, the pressure on the strut mount is significantly higher than for street-only cars. As a result, catastrophic front strut tower failures are more common in GT/RS models compared to standard models.
To address this issue in Porsche factory race cars, they are equipped with Porsche Motorsport strut tower reinforcement plates designed to prevent such failures. These reinforcement plates effectively increase the strength and durability of the front strut tower mounting points, greatly reducing the risk of failure.
The performance results are impressive, with race cars rarely experiencing strut mount failures compared to street cars.
To bring this level of durability to GT/RS street cars, Silver Rocket has customized these Porsche Motorsport race car strut tower reinforcement plates for a direct fit. Now your GT/RS street car can benefit from the same structural reinforcement as a factory race car, allowing you to enjoy track time with confidence and safety.
