After Dark Speed High-performance, light-weight direct replacement adjustable engine mount kit for all 97-13 C5 & C6 Corvettes including Z06 and ZR1.
This unique mount design still uses bushings, but they are smaller and firmer than the large factory rubber isolators. They offer a nice balance of vibration damping vs. engine movement for most performance street, autocross, and track day applications where additional strength and support is desired without the extreme harshness of solid mounts.
These mounts come pre-assembled to position the engine at the original factory height, but also include a unique slug system to easily lower the engine in 1/8″ increments. The engine can be lowered a maximum of 1/2″ from stock. This adjustment is very useful to help gain clearance for aftermarket intake manifolds while significantly lowering the vehicle’s center-of-gravity at the same time.
This mount assembly is lighter and smaller than the factory mounts for better header clearance as well.
Fully developed, tested, and tortured on the After Dark Speed C5 Z06 autocross/time attack car featuring a 700hp LS7 engine.
Installation hardware and instructions included.
100% made in USA.

Customer service was great. Order shipped quick. Great value and the change to the car was better than expected. Wife no longer braces herself for the expansion joints and other Ohio road issues.

Brian was AWESOME to deal with, I changed my mind a few times on what I wanted to do with my c6z.. You can go down an endless rabbit hole when you get into these cars “while I’m in there “He was right there with updating pricing and I couldn’t ask for more.. Parts are parts and they will fail but it’s the service that sets the bar for a big purchase.. I haven’t driven the setup yet as it’s still being built but I’m sure he a phone call away to get it sorted..

Great customer service as always. Was on my doorstep within 48 hrs.

High quality parts with installation pics to come

Great support team helped me get the parts needed and got my order within the week.

Balancer was exactly what I needed. Everything as described and fast shipping. Thanks guys

Team went above and beyond to locate the part needed to get my can back on the road asap.

I finally got to install the intake which literally took 10 minutes. The power and launch difference was insane! You can hear the turbos spooling a lot better as well. I’m amazed by the difference just from the intake

Great product and communication.

I went with the super low, extended rear shocks , Swift 9/7k upgrade and absolutely love the stance and how the truck rides. It’s tight in the corners , smooth driving down the hwy and not bouncy at all. Thanks to Brian for getting me set up.

Completely changed my car

Everything seems in good condition and good quality, appreciate the help from brian for all my questions and to setup the shipping to canada
