Pretty self-explanatory

And while I'm at it, what do you think are the max rates that the stock ITR struts can handle?

 

Front springs are linear rate, 4.4 kg/mm (245.872 lb/in), and rear springs are progressive rate, 2.5-4.4 kg/mm (139.7-245.872 lb/in).

FWIW the Spoon progressive rate springs which are designed for stock ITR shocks have rates of:

front 6.5 kg/mm (363.22 lb/in)
rear 5.5 kg/mm (307.34 lb/in)

 

Thank you.

There are some H&R race springs listed on the King Motorsports site - does anyone happen to know the rates of those?

I have a friend with an ITR and he wants the H&R race, but he would also like to know if the O.E struts will be okay or not.

Thanks again!

 

Hey Tom, would be best if we just called King and asked. Thanks man.

 

Are you sure about that? I thought the progressive rates were of the front springs

I just doubled checked. You have the rates backwards. front is 160-240, rear is 240.

As a comparison to spoom springs i usually throw in that H&R sports
have a comparative spring rate: 360 in front, 320 in rear.

and i'm sure with any spoom/aftermarket spring,

the "max" rate the spring can handle is probably around 350 or so.

really i think the shocks can handle even more if you want to sacrifice shock life by more Shocks for me are considered a wear item

I stand by my original statements.

 

I've got to go with Reid on this one, the rears are softer as well as progressive.

 

I read that they were 225 lbs front, 180 rear. Mine now are 500lb front 600lb rear, the speedvision integra is 800lb front 1200lb rear. I have a harsh ride but no body roll in the corners with a very predictable amount of oversteer that allows me to basically rotate the car slightly if I want to point it where I need it to go.

 

Exact rates are posted above. Why did you go with such soft rates?

You sound like a car salesman.
