This seems to be an never ending topic here. I am building a street/drag car. More street then drag. But what the BEST apex seal to run. After reading numerous of threads and advice from people I know I have narrow it down to ALS 2mm seals or RA super seals. which one would be better for my build. Money isn't really a factor I just want the BEST. Thanks

 

if money doesn't matter then get ceramic seals from NRS motorsports in canada

 

I did research on them and I didn't read anything really good. I rather go with either ALS or RA.

 

Both of your choices are good...only read good things about them. I'm no expert but at this point it may just me personal preference.

 

I think am going to go with the ALS. I just keep reading good results from everyone that uses them

 

My cousin has ALS and he search for the best and he says their his best choice. So far

 

That why am gonna go with them. Everyone who has them never has anything bad to say about them.

 

after seeing the RA super seals in person for a customer's engine we sent then back,and the second set we had to surface grind to get the into spec,seems to me that their QC needs to be improved.i myself am running the 1 piece ceramics from NRS.

 

The thing ceramics everything needs to be in like New condition for them to work at their best. That why I shy away from them.

 

I run them in my summer car a 76 Cosmo with the original Cosmo rotor housings....they work great! Street ported w/51 IDA

 

Sure Glassman, but what do you know about ceramic apex seals...

BTW, NRS seals in a 12A in an EP level prep car. Love 'em. Soon to put some in a 13B if i can get the time to pull it apart.

 

Goopy seals are good..They also make them a oversized to account for slightly worn rotor groves...can handle high boost without breaking, people have cracked irons and dented rotors and they are still usable just like ALS..but the advantage is goopys come oversized.

Goopy is what I will be using in my build. Goopy and ALS both have a good track record.

If my rotor were worn I would've went eith goopy, but since there not am going to get some ALS 2MM seals. I've talk to primordial who r currently using them and they love them. Thanks for everyone input
