Opinions of Builders of Superformance Cars

[Mark IV]

There are several good installers with SPF experience on the East Coast but based on your location and our experience I would put Olthoff Racing in a solid first place. Dennis has done numerous cars for our customers. He will refuse to do something that does not work and has no problem with telling the emperor he has no clothes.

Custom color/stripes are available on an SPF vis factory order. Recently there have been several MK IIIs done with unique colors from the Lambo/Porsche/Etc. palette as well as some unique stripe colors and patterns. A recent option is a "diamond pattern" sewing for the seats and tunnel. We can provide a chassis to meet your concept with the boundaries of the basic product. Headrests, twin roll bars, etc. are available. As to changes in the dash, etc. they will done by the dealer or installer. We have done heated seats in a MK III for a customer, basically anything that does not compromise the factory integrity is available.

Our experience with a hardtop mostly involves delivering the car with the top which is then removed to a garage corner where it resides for the duration. We really only have had one customer that used his hardtop much....and he winter drove his car here in New York (a balmy -2 degrees as I type this) so you may want to reconsider investing the cost of a hardtop in other areas. Really, if you need the hardtop to drive, you likely are not gonna take the Cobra on that drive.

The SPF suspension is very adjustable with coil-over shock/springs which make ride height easy to set as well as full caster/camber adjustment as compared to some chassis' that use "take-off" sedan type setups.

The horsepower question is dependent upon your suspension and tires. 15", 17" or 18" wheels? With the right stuff you can put down 800 HP. With BFG TA's you can't use 400. Don't be a "bench racer" bragging about 750 HP in a car that you can't drive even mildly hard because it doesn't work and can't handle the power. Balance is the key, good linear power, confident suspension and proper chassis setup with 500 HP will beat a poorly setup 800 HP beast.

I would concur with Rick, in that if your are considering an SPF and are in the south east, then Dennis Olthoff is at the top of the list. Dennis and Rick helped me with my build, and I have no complaints. There is a ton of experience and support there, and as Rick said, Dennis will let you know if he thinks that you are going in the wrong direction with your build. I would rather have someone tell me that he thought I was making a mistake, than someone who would kiss my butt and tell me what I wanted to hear just so that they could make some money.

Do your research.
