Dumb question: Bike Rack Installation - should the arms be stretched?

I have a Topeak super tourist disc bike rack - should I need to stretch the aluminum arms out before allowing them to clamp down with tension on my rear dropouts? If I don't stretch the arms I can't make the rack attachment points meet the rear dropouts. The rack is too narrow. I assume that's fine, I just don't want to damage rack or frame.

Many thanks.

I'm not sure I understand your question, but anything short of permanently bending them would be ok. Some amount of permanently bending them would probably be ok.

Yeah, it's confusingly written. Basically the width of the bike rack is too narrow so I can't make the rack attachment points on the arms of the bike rack align with the rear dropouts unless I stretch the arms about an inch wider. This is easy to do.

Yes, spread open the rack legs to fit the drop outs.

I did that on my disc brake bike and haven't suffered at all. I even had to go wider with spacers (thanks Ace Hardware) to get it around my brakes.

I've seen racks made for disc brake bikes, but I didn't like them.

Yep, had to spread mine out to fit the rack mounts also.
