Ford Racing Boss 302 Springs...

[Justin]

if you lower it to springs have to be someone stiffer or else the car will bottom out too much. I don't believe the P Springs oh really all out race spring rate sorings.

anyone have spring rates for the p/k/t/stock? the 55D springs (brembo.com rear only lowering springs) lower it just enough to level the car out and retain the same spring rate as the brembo stock springs. which is softer then the boss so I would think they could do level type drop for the rear and keep the stock boss spring rate

thanks guys looks like the eibach pro kit is the closest to the boss stock just a hair stiffer. I may be able to live with that.

Has anyone installed these? If so what's your opinion of them?

the day is much more enjoyable if you just shoot the people that annoy you. Makes it pass much quicker and theres always a few laughs as they scramble for the exits.

I am looking for a drop that keeps it handling exactly the way it is now just lower. I dont want it stiffer at all hopefully these are those springs

Check out BMR. Their springs lower the car as well as provide a close to factory ride.

 

[fun4me]

Hotchkis springs have a close to stock spring rate.

 

[Boss 738]

Just finished putting FR K Springs on

 

[Champale]

Boss738 - It looks great! More pics please and any driving impressions yet?

Thank you!

Ill take some more pics today, honestly i cant tell the ride difference. I put 50 miles on it yesterday and its been driving like normal. These springs dropped it an inch and a quarter all the way around. Still will settle some I'm guessing but doubt it will get to inch and a half. I absolutely love the look, the 4x4 look Ford had was kinda silly

And for those thinking about it, install is very easy and a spring compressor is not necessary

whats their spring rates?

Do you have the trans scoop installed?

 

[fun4me]

whats their spring rates?

The BMR springs are 160 rear(linear iirc) and probably 160+(progressive) front. I like Hotchkis, they're 180. Probably to soft for any type of serious racing, but my gt is 99% steetcar.
