Ready to buy coil overs

[IdahoZ]

Well I think I am to the point that I am ready to start work on the suspension and was trying to figure out what length and rate of spring I need. The car will be used mostly as a street rod. I would like to have it handle good, have decent tranction but be steetable without a bone jarring ride. I like the looks of the larger wheel so I am thinking of going with something like a 16 x 8 wheel with a 5" offset and 225/50/16 tires on all fours.

 

Here are my specs and what I was thinking. Any feed back would be appriciated.

 

1972 240Z (2355 lbs) minus engine and 4 speed tranny (525 lbs) which gives me a starting weight of approximately 1830 lbs.

 

add 547 for a 400 sbc (575 lbs minus 30 lbs for aluminum intake/waterpump/gear reduction starter). Engine will be mounted in the JTR setback position with crossmember spacer.

 

add 140 lbs for a T56 tranny

 

add 16 lbs for an R200 diff to replace the R180

 

add ~50 lbs for misc stuff like frame rail connectors, strut bars, bigger wheels, LSD, etc.

 

That gives me a car that will weigh approximately 2580 lbs when done. That is about 645 lbs per corner. I do not know what my front to back weight distribution will be?

 

I plan on using a 1" front sway bar and 7/8" rear (as these came with the car).

 

I will running around 375 hp and 400 lb/ft of torque.

 

With the wheel and tire combo I plan on using I thought I would run the following for my coil overs:

 

Front

10" coil overs (probably from MM or GC) 180 lbs with stock hat.

Section strut tubes 1.5"

High quality strut like Carrera

 

Rear

10" 220 lbs with stock hat

Section strut tubes 1.5"

High quality strut like Carrera

 

Opinions / feed back?

 

Thanks.

According to post #48 on this thread: http://forums.hybridz.org/showthread.php?t=106354&page=3 the Carreras are NLA.

 

I'd be really tempted to try the Bilsteins without a revalve at those spring rates. If that doesn't float your boat you could do the old standard Tokico Blue or Illuminas. Regardless, that thread should help a LOT. Great info in there.
