opinion on what camber plates to run

[Best_name_available]

I'm getting the GC conversion kit for my 89' 325is that i am going to run with bilsteins and i am not sure what camber plates i should get, the car is going to be a serious street car and will see some track days possibly auto x. i think im going to be going to go with 6" 400/600 rates, let me know if you think thats to stiff as it will be driven 30-45 miles about 4 days a week (my other car is 65' chevy nova wagon so this will be my "reasonable car") so before i order my conversion kit i wanted to know what the best camber plate would be and if the spring rates seemed to stiff (or to soft) as the car will be on the street most of the time. i have heard that the GC camber plated make sounds and "pop" at low speed cornering, and i really don't like the sound of that (no pun intended) but maybe its not true id love to hear your experience with them or any other plates.

ps:I'm brand new to the forum and couldn't find anything directly related to this but thank you and I'm sorry in advance

GC is your best bet. I'm 440lb/650lb and it's very streetable.

yes Dont mix and match shit if you got gc coils use gc plates

ok then im too excited to hold off any longer anyways, do either of you have any experience with the sound?

For street use their touring camber plates. I have them installed and they are silent, their race version can make noise.

Another vote for the Ground Control Touring plates. Love them!

Yep.....GCs. I am pleased.

I have no experience with the gc's, but I have the Ireland engineering street adjustable camber plates that use the stock upper strut mounts. Stock comfort, easy to install and service, and cheap too!

They do add ride height (about 3/8th inch), but with German Engineering coilovers on shortened strut housings, and the adjusters all the way up, I was still lower than I wanted for daily driving. The added ride height up front was a perfect solution for me.

GC here. the ix plates are a work of art.

you want a short stack height. more travel means either you can lower it a bit more or have better ride quality because you don't crash into the bump stops.

you want a short stack height. more travel means either you can lower it a bit more or have better ride quality because you don't crash into the bump stops.

While that's correct in theory, it's too obtuse in this situation. You misunderstand these plate's purpose. The "street-adjustable" plates are made to work with the stock strut bearing so you don't get any increase in vibration/harshness (given the stock rubber mount). It does sacrifice stack height for comfort. Given the purpose of these plates, it's unlikely you'd be in a situation extreme enough to actually have the difference in stack height mean something in reality.

------------------------------------------------------------------------

For a more accurate comparison of street performance plates you'd look at the GC Touring plates or the IE Street/track plates.

CONTRAST: The upsides of both the GC Tourings and IE Street/Track:
You've got the spherical bearing encased in urethane that dampens a good portion of the shock (unlike a spherical bearing pressed into an aluminum housing commonly used in race plates). You can also run both with stock 5" springs.

COMPARE:
Between the GC Tourings and the IE street/track. The GC Touring's have shorter stack height and caster adjustments, but the IE Street/Track has more overall camber adjustment (but still has a slightly shorter than stock stack height). I wouldn't hesitate to run either plate.

EDIT: fixed.
