Default Extended wheel studs ARP 100-7715

Anybody using extended wheel studs? Searched ARP and found one that is close to fitting. Seems the 2GS uses them but can't confirm for the 3GS. I don't want to go with Ichiba cause of the horror stories. Yes, some have had some success, but most don't. Trying to fit some 19x9.5 +22 in fronts but they're sitting on the calipers. Purchased some 5mm spacers but the lug nuts aren't sitting in far enough to be considered safe. I believe the wheels are mid disk. Brand of wheels is not in question. Just making the car fit the wheels lol. Please don't come in here saying "buy some wheels that fit" because that's an idiotic thing to say. People here customize their rides for a reason. CUSTOM. If that's the case then everybody should stick with oem wheels. Understand the question, not make some genius remarks. The ARP studs part number is 100-7715. If anybody has used these wheel studs, please chime in on fitment. If anybody running this width with this offsets or lower, what did you do to make it fit if you ran mid-lo disk? Even thought about shaving the corner of the calipers a tad to make it fit but if i can go with the studs, that would be better. Before anybody coming in here flaming "don't do that cause that will mess up your brake geometry," please don't say it and do your research. You can even call lexus and speak with a true lexus technician and they will tell you our brakes a oversized and a little trimming will not make any difference. Again, this questions is strictly for those that have went through this, not for the bandwagoners. Thanks in advance.

I haven't had this problem (still running stock 18s) but I remember reading a post a while back about how the stock brakes do stick out further than many other calipers, even compared to F-sport brakes and other BBKs. So it may be a good excuse to get a BBK if you're planning to upgrade at some point anyway!

Oh and sorry in advance if I'm being a bandwagoner

Lol not intended for insult, just trying to get straight to the point. Well for those that recently purchased brakes from Lexus prior to November 2016, bad news is there's an update on the brake system itself and you'll end up having to buy a whole new brake setup if you're dealing with the "squealing" noise. But the good news is, aftermarket BBK (Wilwood and etc...) is hella cheaper than OEM brake system. Now you have an excuse to upgrade. How I know of the updates? Lexus insiders lol.

Why would it be an overkill? Is it because of the cost? Please explain. It's a reputable brand and not one has had a failure. Ichiba on the other hand is a hit or miss. I prefer not to deal with the headache and the time later down the road if it was to crack or bend.

I'm almost there broski. Been researching all night. So much mixed info here on CL on the 2is and 3gs and it's mainly from people that haven't done it and speaking out the side of their neck cause they think they know everything. I might as well be the test dummy buying it and reporting back with some true information to HELP other members that will run into this issue.

ARP i think is over kill for strength/price wise for a street car. You can go to any auto parts store and match up a set of dorman studs, I never used ichiban but have used dorman and they are strong as oem.

The ARP you posted appear to fit, but I think there too long for what you need. stock length is 40mm or 1.578 and the ARP you posted under head length is 66mm 2.6 in

I would look for something 45mm unless you plan on running non-closed end lug nuts.

The studs themselves are basic japanese size so an auto parts store should carry something for you.
