Annex Suspension has begun development on Fastroad Pro Coilovers for the GR Corolla.
They're using my car for development. They gave me permission to post this on here, they want to see what you guys think and they want to gauge the demand.
I can't share too much yet.
Here is more information on their website. Feel free to contact them for more information or any questions here.

Hopefully I can convince Grant, the owner of Annex, to answer questions.

Here are some of the improvements I've noticed over the OEM suspension:
- Improved handling and braking feel.
- Better turn in response.
- Reduced understeer and body roll.
- These coilovers are much more comfortable and compliant on the road than the OEM twin tubes.
- Slightly lighter and smoother steering feel from the spring perch bearings.
My thoughts and opinions:
- The OEM twin tube suspension is definitely a limiting factor for the car. It holds back so much potential this car is capable of and my theory to that is the GRC has a dual purpose, like the WRX; Rallying and street/track driving but not focused on either. I know the Morizo improves upon this, but how many people on here have been in one or own one here? 3?
- IMO, the OEM suspension is misleading because the ride harshness can be mistaken for suspension stiffness, but it is actually on the soft side. As we all know, this car has a lot of body roll and understeer.
- We learned that the rear sway bars are quite soft because the car still has some push in the rear.
- I would SKIP getting springs, they're not even worth the money. 1.) OEM twin tubes are not great 2.) You'll end up wanting to get better shocks for them and they're not adjustable.
Hopefully I can convince Grant, the owner of Annex, to answer questions.
