RE: hardened seats? |

Just an opinion based on things heard and read over recent years. Hardened seats are a good idea if you're planning on a driver that uses nothing but unleaded pump fuels. It sounds like this is what you plan so you'll need the hardened exhaust seats. Higher compression for racing only? The use of leaded racing fuel will eliminate the need for the hardened seats. Occasional racing with 10.1/higher compression ratio, you'll probably use racing fuel for race day and some for street driving mixed with high octane unleaded. I've understood that even occasional use of leaded racing fuel eliminates the need for hardened seats. |
