So i am planning my rebuild and am trying to decide to go with the 93+ side seal springs or normal fc replacement springs. I have read a lot of people saying the 93+ are stiffer and create a better seal. However i have also read that the 93+ springs are the exact same as the prior years just with a new part number and greater price.
So i am not asking for advice or opinion i am just asking for anyone with actual evidence of a difference, say a dyno sheet or something other than the price showing that they are stiffer.

-Thanks

normally it is the FD corner seal springs that people buy, not the FD side seal springs

FDs are stiffer and a lot more money 2.

Atkins doesn't specify there being a difference they sell them 86-95

Mazdatrix does sell them as being different
86-92
11-C170-N326: $1.74

93-95
11-C170-NF01: $6.75

I'd say call Mazdatrix and ask them. While on the phone ask them if you can buy one spring from each. I'm sure they have spares around. Two individual springs + shipping won't be much at all.

You really believe that springs are creating sealing pressure?
