We're headed down a different path for our FD radiator offerings and planning to work with a known supplier (more coming soon). The plan is that we'll provide the shroud, surge tank, intake and accessories and have a radiator drop shipped to you directly. We're planning on having users source some of the bigger components themselves, notable fans and the K&N air filter.
As such we're selling off our remaining inventory of spal fans. This is the 30102052 fan assembly. It's our favorite fan setup out there and we designed our radiator kit around this form factor. The rubber speed flaps ensure maximum airflow when moving while the fans themselves are both powerful and an ideal form factor for v8 rx7 use.
If you're in a hurry you might consider our radiator piece part offering as that's get you 90% of the way there.
