Spectre Super 7 SCCA D Modified

[Locofinn]

Hello all! I've been working on this scratch build Seven clone off and on for 4 years. This is my first attempt at building a car. This car will only be used for autocrossing and trackday fun. I'm only one month from the first track event and cannot wait to drive this. I want to share a few pics to show you where I'm at in the process. It may be a crude beast but it should be fast when I get the full race motor in it. It weighs a bit heavy at 1,320 lbs wet right now but I can work on that.

Amazing!

[xcarguy]

I definitely do like the interior of this car; looks 'all business'! :hurray: How about sharing some more details about the build.

[Automoda]

Look at that stance. It sure is going to stick.

 

The cage is part of the frame. And all those new shiny parts.

 

Cant wait to hear your racing reports! You should tell more about the project.

Very nice... I like the rear fender style. Great workmanship!

[xcarguy]

Locofinn,

 

Very impressive craftsmanship! Are you sure this is your first build?

[Locofinn]

Update photo before the first track day.

[Croc]

Wow That is a seriously well thought out car with immaculate workmanship. How long did it take you to get to this point? I will be very interested to see how you find it on your first track day? It is almost too nice to put out on track it is so beautifully done....almost

[Locofinn]

I figure about 600 hours over 4-1/2 years. Check out the video in the Seven Videos section. It worked very well. Needs some tuning but nothing major. It will never be truly completed if you know what I mean.

[MichaelD]

Wow! great job. I love the rear fenders into the spoiler. When and where is your first autocross?

[Kitcat]

Also love the rear fenders' "cone catchers" (I will take 2:)).

[Locofinn]

Photo update.
