I want to make it a nitrous car in the future and I plan to start taking it to the strip once the weather improves and was looking for suspension setup ideas? I was thinking of trying to keep it a leaf spring car because it seems like the cheapest route to go. I have been looking into calvert racing and like the caltracs and have read good reviews on their products but was just looking for more ideas... I want the car to have a aggressive lowered look as well. I plan on using 275/60/15 drag radials in the rear. Thanks

You can build a 4-link quite economically & it will be the best suspension for drag racing. I suggest you make your own 4-link kit ... and use individual brackets. With that low-ish level of power, you need the top links to lift & plant the tires with all the leverage they can.

Purchase brackets that will place the multiple top link holes in a range of 5-7" above the rear axle centerline. Use similar (or the same) brackets for the lower links to place the multiple lower link holes in a range of 5-7" below the rear axle centerline. Make sure you can run your lower links close to level in one set of holes & downhill (going forward) in other sets of holes.

For a baseline set-up, run the lower links slightly downhill to the front (0.5-1.5° downhill) & place the top links to achieve an instant center about 54" in front of the rear axle centerline. From there, you can test & tune with top link angle to find where the car is really happy on the launch.
