Custom BC Coilovers

[ShawnB]

Looking for some help/input for those who know a bit about our suspension.

I am looking to order BC Coilovers very soon, and BC allows custom spring rates and now offer an Extreme Low kit as well. So my thoughts were to get the Extreme Low Kit at no extra cost, and do a custom spring rate which is free as well. Standard Spring rates with the BR style coilover is 6kg Front/4kg Rear. My thoughts are to go stiffer, but not sure how much.

7kg Front/6kg Rear
8kg Front/6kg Rear

I am open to any combo and I believe the available rates range from 4kg up to 17kg at a 1kg increase.

Thanks!

Plan to order in a few days, any input at all? Those with stock BC Coilovers what are your thoughts with the 6k/4k springs? I was thinking 8k/6k now....

JusticePete went with 6kg front and 8kg rear for his Sonic build using Pedders coilovers.

And From what I've been reading, JusticePete is a suspension master and knows his stuff. I'm attempting to learn a thing or two myself

I'm new to Chevy/Sonic world … but have yrs of experience a-x'ing, PDX/HPED, and TT'ing front wheel drive vehicles

the rule of thumb, unless the cars wheel base is so short (like my CRX) that it doesn't need to be rear biased, is to put the stiffer springs in the rear.

this isn't the ONLY way to do things, but stiffer front ends (springs and/or sway bars) than the rears lend themselves to continued understeer …

so those kits are designed with safety in mind (understeer is safer for most folk than oversteer) which is why they come with the stiffer springs on the front

take all this with a grain of salt … like I said, I'm new to Sonics … all my past experience has been with Hondas

I went with Cx racing Coilovers with default setup of 6k front, 4k rear. Felt like saving a little money since i dropped 3000 at one shot.

the Q-08 kit for the sonics come default 6Kg front and 3Kg rear. I'm not sure I can justify 1k for the kit and I don't know how cx racing is with their products.

Bc doesn't make extreme low for the sonic. As that's what I was told. I am curious as to how can I get rear lower
