Why use 'camber bolts'?

[Geordie-Chris]

Looking to set up my geometry on my 172 Cup this weekend, I'm lucky enough to have access to a laser alignment machine at work so can do it all myself.
I'm wanting to increase the front camber for an upcoming track day, and was wondering do I NEED camber bolts? Only looking for -1.5° nothing too extreme!
Why not just elongate the shocker bolt mountings like a lot of manufacturers do to gain the camber?
Just after people's opinions, ideally from anyone who's tried it, had it done etc so I can order the bolts tomorrow if necessary.
Thanks,
Chris

not everyone has the tools to accurately elongate the holes. Its a simple solution to use camber bolts.

I got mine from Kam racing last year. they're cheap so the hassle of elongating the holes is not worth it

On a plus side,it will not move with camber bolts.as long as the little washer is fitted correctly as this takes up the free space behind the cam.
Slotted struts can and do move,even if done up megga tight,fact.

good point Tony! Probably the best reason there is really..

there are coilover kits with built in camber adjustment, not sure how they work but I saw that the hole which carries the adjustment is oval. This is one of the reasons I went for gaz coilies an still using the camber bolts I had
