Originally designed for use in professional motorsports, inverted monotube technology has many advantages over upright monotube dampers. The 45mm strut shaft offers increased lateral rigidity over competitor’s upright dampers that use 20mm shafts. If the shaft is not stiff enough it can cause the damper to bind under heavy loads and limit the suspension travel – leading to premature wear on the shaft seals & piston bands, causing oil leakage. STANCE inverted monotube dampers offer exceptional ride comfort without sacrificing performance.
Their piston has been developed to deliver a large range yet responsive adjustments. Even with this large adjustment range, each click is even and precise to provide excellent fine tuning ability. Winning races has taught us that compliance is key, even for competition setups. They know how allowed us to fine tune the valving balance providing you the ability to go from compliant & forgiving to firm & responsive with just a few clicks of the knob.
Digressive valving produces high damping forces at low shaft velocities & softer damping forces at high shaft velocities. Low speed damping gives better control of the chassis movement & provides quicker feedback to the driver, enhancing overall feel & confidence on the road & track. Digressive high speed valving profile blows off big bumps forces for smooth response, giving optimal chassis balance for maximum grip.
The Stance damping adjuster knob, or “Clicker”, is designed to offer an easy and convenient way to adjust the damping of your coilover. Their heavy-duty adjuster gives a very positive “click” for each of the 16 levels of adjustment, making it easy to keep track of your personalized settings.
Everything from wheel clearances to ride height adjustment is taken into account during the design process to make sure you experience a hassle free install of your new Stance coilovers.

from 47 reviewsGreat product and service from Brian

I just drove the car for the first time since installing and even on cold roads and little adjustment they are a night and day difference from the factory leaf springs. Car is a higher hp nitrous car and these are exactly what it needed. Can't wait to see what they can do with some adjustment and tuning. If you're on the fence about getting them just do it you won't regret it.

Kit looks great can't wait to install. Don't forget to add the Wilwood stainless brake line kit to get the best performance.The best part was the service Brain gave with this purchase. I would recommend FI Performance to anyone looking for great prices and wonderful customer service. What other performance parts site do you know where the owner himself will contact a first time customer and walk him through the options available?

You really do get what you pay for with these. Steering feels sharper and smooth. Weight shifts feel smooth and planted. Ride is nice and comfortable but tightens up when you need it to. Build quality is also super great. Nice and sturdy with quality materials. Genuinely satisfied with how easy the entire process was from ordering,shipping and installing these coilovers. Will definitely be recommending this suspension with all of my bmw friends on discord 👍 shoutout to Brian for helping me throughout this entire process

ECS Corvette C5 Automatic Trans / Rear Diff Brace

Installed these on my 2012 c6 and it definitely feels 100x better to drive than the stock leaf spring setup. Install wasn’t bad… it’s just bolts. Brain reached out after purchasing to go over the order and make sure its exactly what I wanted, I was very surprised, awesome customer service. All in all great product and service!

Great upgrade to the old worn out leaf springs. Feels like a modern suspension now. Excellent quality and workmanship. Definitely recommend

Great communication and fast shipping!!! Brian is quite knowledgeable! Let him know your set up and he’ll get you connected with the right product!

A+ Thanks!

Never fail, feel great! Pair with swift springs and you’re riding on a magic carpet ride. Makes all the hunnies holla when you’re cruising down the street in my c6.

Quick delivery, great product, great price!

Fitment was absolutely perfect. The quality of the Toe Arms is a thing of beauty. A thousand times better than finding stock replacements. I can't say enough about how incredible well made thay are.

The Brey Krause Harness bar was exactly what I was looking for, packaged very professionally & a breeze to install. Brian is top notch. For any corvette needs, I’ll always recommend FI Performance. Impeccable customer service, the products are here on time and they are always great quality. 10/10 recommend!
