I have Spoon springs with std shocks. Only about 10-15mm drop and a little stiffer.
I think this would do for me on the road. Coilover IMO is overkill if it is a daily and occasional track. EP stock is very able, but thats just me :)
Money better spent elsewhere. But everyone does things differently tho!
Enjoy it, EP3 is good regardless of what is done!
