rear suspension? 4 link? caltrac mono leaf? street lynx?
the car is mini tubbed with/6 springs in the rear with some old school 50/50 competition engineering shocks. it works well at the 400hp mark. the tire is a 325/50/15 et street r radial.
Don’t know what you want to use for a 4 link, but to get one in there is a ton of work. I used and unequal 4 link because the shorter top bar made it easier to get it all in there.
Some pretty fast dudes running leaf springs. I think I’d spend the money on getting rid of the /6 springs in the rear. You need a much higher spring rate back there than that, especially when making the power you are talking about.
So I’d go a Calvert split mono spring. Then I’d order a set of Assassin bars. They have the most adjustability of all that style of traction bar out there, and you need some adjustability.
Then I’d spend the money on some Viking double adjustable shocks for all 4 corners. Again, the ability to adjust as much of your chassis as you can is a big deal.
Then I’d invest in an ignition where you can ramp in the power to help control the application of power.
I’m a huge 4 link fan. Making them fit, and fit correctly is a beeeotch. The learning curve with a 4 link is steep. It’s not a set it and forget it system. Just getting the instant center where it should be is work. And it’s not where most people think it should be. Then the tuning begins.
You should also get as many chassis books as you can find. Read them all. I always plot out a 4 link on the shop floor and then move it paper after that. You need to know what every hole combination gets you for IC. You can’t guess. And every IC will take different shock settings.
