Lethal Performance NEW PRODUCT: ISC Suspension S550 Coil Over Kits

[Derek@Lethal]

Lethal Performance is really excited to announce our newest manufacturer, ISC Suspension and the 2015+ Ford Mustang Coilover set. This is a set that ISC has been developing in secret for some time and we’re so excited to be able to show you all the new finished kit and even more excited to get them out on some Mustangs. The 15+ Mustang coilover kit features the same great adjustment range that all of the other ISC coilover kits come with including:

• An industry leading 5 year warranty

• ISO 9001:2000R certified

• 32 way adjustable damping

• Singe Cylinder Mono-Tube Design

• 3 Valving options utilizing 3 different shim stacks

• Piston Rod Design

• Front Camber Plates

• Thrust Bearings

• Sport Springs with less than 5% deformation (Swift also Available)

• Independent Pre-Load and Ride Height

• Aluminum bottom brackets

These kits are now available and can be purchased from us here at Lethal Performance.

It is important to make sure you also register your product after purchase with ISC otherwise you will not be eligible for ISC’s 5 year warranty.

These kits kick ass all around and are available with 3 different valving settings, Comfort, Street and Track. They are also far less expensive than most any other kit out there while still performing at the top and offering one of the best warranties.

Let us know if you guys have any questions about these kits or if you'd like to place an order.

Thanks :cheers:

Ohhh! How well does the Street valving ride? I don't see Comfort being as focused as I'm looking for, but know Track will probably be too much. Also, what's the minimum drop?

These are legit, I've had ISC stuff on different platforms. Super reasonable price for a good set of coils.

Street is going to be the set-up that is most common as it's kind of a do-it-all valving. It still gives a good ride and sharpens the handling at the same time.

Thanks. Hopefully you can keep reasonably close to stock ride height. I'd like to have less than 3/4" drop.

To answer your question about ride height, you can get the car to stock height and lower it as much as 3" from stock.

Can you give us spring rates for the Comfort, Street, and Track models?

 

[madsedan]

Also Derek, can you pm me a price delivered to 75087 for the Street set-up?

And what the cost bump is to use Swift springs?

 

[Adaraas]

Are the track options more oriented towards road racing or drag racing? I'm assuming road racing but you never know.

 

[byklin]

How many inches is the car lowered in the picture?

 

[madsedan]

FYI, pricing is up on Lethal's site, but still need to know the spring rates.

The reason I want to get the spring rates nailed down is that in the past there have been issues with ISC shipping the wrong spring packages, or rates that were just inappropriate for the car, etc. I'm sure Lethal is insuring that their N1 package is complete and correct but would like to know what spring rate Lethal spec'd for the Mustang.

Spring rates?

 

[Derek@Lethal]

Comfort and Street use the same spring rates, just different valving in the struts and shocks. Those rates are 504 in/lb and 784 in/lb front and rear, respectively.

The track is their most aggressive and it's geared towards road race/auto-x but ISC did say that in their other applications, customers do use this valving on the street as well. The rates for the track kit are 560 in/lb and 896 in/lb front and rear, respectively.

 

[madsedan]

Thanks Derek, exactly what we needed. I am used to dealing with spring rates about 100# lighter than that on my M3's from several years ago but those cars were 400-500# lighter so this is probably perfect.
