Default Valve adjustment DIY

I saved this shim kit in my eBay watch list from ages ago

https://www.ebay.co.uk/itm/Hot-Cams-...53.m1438.l2649

Can anyone tell me if this is the right kit for an e46 M3 valve adjustment?

I used the Wiseco VSK4 shim kit when I done mine a few months back. I ended up buying two kits as you only get 3 sizes of each sim, 23 different sizes and didn't want to risk being short on a particular size.

Size is right, I also used the Wiseco kit. Managed to get it from america on offer for about £33 and didn't get hit with taxes

Wiseco ones are the right ones to get. As mentioned, you might want to consider getting 2 or 3 sets to make sure you have enough of the right size shims.

Sure, but if you need more then youíre out of action for a week while the second set comes from the US

You are also out of pocket if u buy 2 or 3 sets and only need a few shims.
The hot cams set on ebay dont take long to arrive.
Can also be ordered individual from the dealers.

I bought one set of wiseco and then figured if needed a 1 or 2 more shims I would just order them from BMW.

For the price of the Wiseco kits VS the OEM BMW shims, does it really matter ? Im from Australia, it cost me about 100ish dollars for the two Wiseco kits delivered vs the 600 + for the BMW ones.

Also you'll have them for the next round of valve adjustments.

Just my thoughts.

Just piece of mind that your valves are not getting over heated due to excessively tight clearance

The engine runs quieter and smoother, especially noticeable at 6-8k rpm, and I'm sure there's a slight increase in performance.

They would want to be all severely out of whack to notice anything. Changing a shim or two is just a placebo effect

Way way to much of a hang up regarding shims,, and paying hundreds of pounds having them done. Feeling the need of a stamp in the book, Iím not saying donít do them,, most would find very minimal adjustments needed,, unless someone previously did a crap job ,,

At my first inspection service owning this car, when it had roughly 100k miles, Redish changed 16 out of the 24 shims. It made a big difference!

It had probably never been done, despite the BMW stamps in the service book.

My M3 came back from it's Insp 2 a lot quieter from the valvetrain, and fuel economy was improved - I didn't ask specifically how many they changed though, I think it was quite a few. I can't think what else would improve FE after an insp.2 (new air filter will help)

I'm sure the car is generally smoother but it might be the placebo effect of spending a lot on the car in one go

Air filter, spark plugs, fuel filter - all will have played a part no doubt. But that being said I did my own valve clearances and 6 needed changing. It sounded very slightly better.. It still needs doing even if there's no noticeable difference.
