Coil Question

[Supra725]

Hola guys and gals...

I have a few questions about coils..

I recently replaced the shocks on mine with Bilisten HD, but I didn't do the coils..

I would like to replace it this summer but I don't know if I should go with ome's or stick with oem's.

Figure, after 11 years of stock springs.. Is time to replace it.

The car will most likely stay on tarmac but with mild off roadings..

thanks.
