PIMPING OUT AN 'I'

fixed
my dad doesnt like this bc it's too pimp

You have GCs on your dd but "xyz"s on your m3... Splain

Unless you mean gc "coilovers" and poop for shocks

[mbonanni]

Talked to Igor yest at Big Socal Euro and he said he likes the xyz more than GC settup. Reppin' his producctt

Both cars came with what they have.
it's revalved billies and GC coilovers on the eta

I have both
the GCs are 1000x better than the XYZs.
the shocks that come with the XYZs are utter trash. once i pay for the car it's getting better stuff. or back to stock

i want to send out my 5lug struts to GC for the full package....someday.

H&R race with billy sports.

Twins ;)

What rates??

[Cabriolet]

H&R race with billy sports.

eww too soft

you need 450/650+konis.
i have an m3, we could pull the front off of that and send them to GC and then trade me your when you get them on.

450/650

[mbonanni]

I could never go softer than what I am at. 550/700

While on the subject, I have had tons of people ask why I opted for softer in the front as that is where the motor is, so they think the stiffer should be in the front. I have never been able to tell them the real reason minus "everyone does it" lol

[Cabriolet]

you know they are actually the same rate at the hub.
the front is 1to1 ratio
the rear is a fulcrum. since the spring is farther in than the end where the hub is, you need a stiffer rate.
heres how it works.
measure the distance from the center of the spring to the trailing arm bolts
and then measure the distance to the center of the wheel hub,
(front spring rate)*(distance to hub)/(distance to spring perch) = needed spring rate.

[Wh33lhop]

"the rear spring is less effective than the fronts, a 700# is more like a 300# at the wheel"

[mbonanni]

So youre saying because the rear spring is not directly in line with the hub it needs a stiffer rate to compensate for the distance?

This sort of has a Physics Torque Theory applied to it? yeah?

the e30 trailing-arm suspension design requires it. if the spring were around the shock like it is on most cars, a lower rate for the rear would be appropriate, but as it's a bit inboard, the spring has to be stiffer to get the same effective rate. think in terms of leverage and you'll get it.
