I also posted this up in the Prelude section since I going to the track on Tuesday.

I'm in the middle of installing some Willwood 4 Piston Dynalite's. I noticed that the stock Prelude caliper is mounted using a 12mm grade 8 bolt. The Willwood caliper only allows for a 10mm bolt. I would also prefer to use a 10mm bolt to mount the adapter bracket also.

Do you guys think a 10mm grade 8 bolt will be strong enough to indure long term heat and punishment. I'm being extra caution's since this is the one part that has to work all the time.

Thanks,

Tony
