What size wrench do you use to remove the back weight on SIM max? Thought I might be crazy when I realized my standard torque wrench didn’t fit.
Correct, it is not the same size. I had one in a regular drill/driver bit kit that fit fine, it is a similar shape hex-head. Just be careful, don't use a power tool to do it. Crank it by hand so you don't accidentally strip it or over-torque.
It's GRK T15 bit
You can get SIM Max weights from The Golf Adapter Store.
Will have SIM weights in stock thus coming week, also for fairways
Removed my Sim Max weight and it weights 15 grams. Sounds right?
They are currently available at billy bobs
So if we wanna play a Max driver at 45 or 45.25 what gram back weight do we need to buy? Looks like Billy Bob’s offers a 17g and a 19g
I am going 45” and picked up a 19 gram off EBay. Billy Bobs 19 is out of stock.
I just bought a 19g from BB's online said it was in stock. Will see thanks
Nice, just looked. They just have updated their site this morning. Last night the 19 was out of stock. Thanks.
I already ordered one in EBay, hope it’s not crap and weights the correct amount.
Does a back weight for the SIM fit in the back weight for the SIM Max?
My Max came with a 17g weight and I’d like to put on a 21g or 22g. There’s an Ebay seller with 22g, 25g, and 28g but it’s $25 shipping on top of the price of the weight.
Very lame but thank you for clearing that up.
To the guys who got their weights already. Is the weight the exact weight as stated?
Bought a 19g weight from an UK ebay seller and it‘s only 17,5g. He claims the weight is measured INCLUDING the screw. I think that’s BS.
Most weights are indeed measured with the screw. The 15g slidable weights in the 2016 Taylormade M1 fairway for example are comprised of a 12g weight, a 2g pad underneath, and a 1g screw. So 17.5g for an advertised 19g weight makes sense.
Thats correct, just like epoxy and ferrule is part of head weight, and grip tape is part of grip weight, we have to include all components, and cant attach a screw weight without the bolt and spacer.
PLEASE DO NOT SEND ME PMs ON CLUB TECH ISSUES - ASK PUBLIC IN THE FORUM.
Unless you are a former Customer or someone i already have a PM dialog with, i want reply to tech questions on PMs.
Correct, the weight is WITH screw. I ordered the 19g from Billy bob and it is 17 without the screw, 19 with the screw. The stock weight on my MAX was 17 with the screw.
Finally found a 22g on Ebay that shipped from within the US and now my SIM head weighs the same as my M1.
Im playing my max @43.75 managed to get 14grams of poly and ordered a 19 gram from billy bobs. If you think the Sims sound good stock I recommend poly. It's all wooden bat crack now.
So does increasing the heel weight in the sim do anything other than change swing weighting? Is there and effect on moi or cor?
I have been told 5-10g more in the rear will increase spin by 1-200rpm. Each golfers delivery is different of course so each persons results will vary.
Interesting reading because I got my sim max on Thursday .. 46.25” with an AD DI 6x .. and even with two massive strips of the wide and heavy lead tape the head still feels light and I am having trouble tracking the head a little throughout the swing
looking at this thread it seems I may need to hot melt ... this head is 195g and I think the 400LST is 208g. Explains the feel difference
I’m at my cottage so no access to my scale and a swingweight measure. Need to sort out next week with my fitter
I will say when nutted this driver is VERY Long .. but need to hit the centre more often
Adding more weight to the back of a driver always increases MOI, but has nothing to do with COR which is a measurement related to energy transfer between face and ball.
The TM tool doesn’t remove the weight. Anyone know what to use? Thanks!
T15 torx wrench
I just confirmed that the screw in my sim max head takes a T20 torx bit. While a T15 might work, it will be loose and could strip the screw head.
Just for the record, but head weight IS part of actual PTR....even if its very small numbers. (i know the question was COR but more ball speed or higher PTR is really the same as higher COR for the player)
If we for the sake of example set SPIN LOFT to 7.0* (very low to maximize PTR), and change head weight from 197 grams to 212 grams (plus 15 grams or 7.6%), we move the theoretical PTR from 1.473 to 1.493...or like we are used to see this values, smash factor moves from 1.47 to 1.49 so those 15 grams gave the 100 mph player 2 mph more ball speed.
So we can say that 3.8% / 7.5 grams added head weight on a driver adds 1 mph ball speed or 2 yards more carry...........on the paper
(from my old notes where i had a excel sheet made to judge the effect of hot melt when going shorter and 15 grams added was kind of a average amount)
Same experience today.
