when installing coilovers, front should be lower than rear?
 

Hi Guys!

I'm about to install my new coilovers, Tein Flex A for my 2018 BRZ PP

Tein official website suggests that recommended drop is -1.4 inch for front and -1.2 inch for rear.

So I guess front should be lower that rear?

Can you guys please give your opinion on this?

My opinion is to not lower below 1". Or if you absolutely must, buy&install also roll center adjustment kit for front & diff riser for rear.

Also on tein's site for 2017+ USA BRZ Flex A i see recommended height not one fixed setting, but ranges, -1.8 to -1 range recommended for front, -1.6 to -0.8 recommended for rear.

what is the reason not to lower below 1"?

Also, do you recommend to lower front and rear at the same height?

It should be what it needs to be for the application.

I have run it both even and with some rake. I prefer with a little bit of rake, feels like it turns in better.

thanks. I will probably do -1.2 inch front, -1 inch rear

If doing Coilovers I would get it corner balanced too. It would be ideal to have it balanced front/rear and side to side

Out of the box, the TEIN Flex A's on the 2018 BRZ should already be set to a 1.4-inch drop up front and a 1.2-inch drop in the rear.

Here is what they look like installed on my FRS:

What part do I need to replace to get it balanced?

wow that look so low, is there any issue with the -1.4 Front/-1.2 rear drop?

any intervention/crashing issue?

Reasons to not lower below 1" are two.
First - to not fsck up suspension geometry, or if you do, fix it back (hence mentioned roll center adjustment kit), second - to reduce CV joint extra wear due too big angle and quicker failures (hence diff riser)

Rake is just one of suspension setting, that works with all rest. In this case, when coilover manufacturer that designed them recommends such, i'd probably would go with that if know nothing better or have data/experience of other setting working better for me.

Still, rake doesn't mean that you also need to overlower (both front & rear). Just that front is a bit lower then rear in this case. If manufacturer reccomended ranges included -1" front & -0.8" rear, i'd probably would go with that, unless you plan also buying/installing other mentioned parts to correct mentioned issues of lowering more.

You don’t need anything. You can get it balanced if you choose while getting an alignment done if the shop is qualified to do it.

Thanks!

Since Tein recommends -1.4inch front , -1.2 rear range, I will go -1.2 front , 1.0 rear!

Well, in url i found, it was, as i already posted in my first port in this thread:
"Also on tein's site for 2017+ USA BRZ Flex A i see recommended height not one fixed setting, but ranges, -1.8 to -1 range recommended for front, -1.6 to -0.8 recommended for rear."
.. so i'd rather go -1" front and -0.8" rear then
