I want to put gears into the car because like most I feel the car lacks torque. After putting it on a dyno this weekend i see what needs to be done first. I am new to this car and to the research of my question. Is the Dinan rear end costing over 3K worth it versus putting a 700 dollar 3.91 gear set into it? Thank you for the help in advance guys.
You'd get the exact same results as far as I know...the key is having a good mechanic experienced or specializing in diffs. No need to send in your complete unit either. Someone else on the forum just completed the switch with the turner gears and was satisfied although he sold his car. You might try searching-he was from new York.
Current: 2008 e60 DINAN ///M5 Interlagos Blue SMG
DINAN 3.91 Differential, Stage 2 Suspension, Free-flow exhaust, Stage III Software, Front strut braces,
High Flow Air mass meters and intakes, 13% Underdrive pulley, RPI Scoops.
But unless I'm mistaken and I missed a few posts in that thread, that thread is about Dinan's 3.91 vs stock. The OP here is asking about the difference between Dinan's 3.91 and just getting the gears through another vendor (for example Turner). There was another thread about that particular comparison but I can't find it now.
In addition to the $700 gears though, you'd still have to get your diff rebuilt with the Ring and Pinion gears, which will cost a couple hundred bucks.
If you go with the Dinan diff, you would exchange your core and end up paying ~$1200.
So it could be cheaper to go with the Ring & Pinion gears, depending on how much it would cost to rebuild your diff. You do get the Dinan warranty though, which is a nice safety net IMO.

Hey Randy, is that correct? I hovered over the description of "Core" on their website (in the product listing for the diff) and I interpreted that as the price is $2999, they will add an additional $1800 to that but then refund that once you hand over the core, so the total price is still $2999.
For example, the stroker engine is listed at $32,999. The core price is $20,000. As far as I know, the cost of the stroker is $33K after core exchange. If you're telling me that it's $32,999 - $20,000 for the core exchange for a total cost of $12,999 to get a stroker, then hell, I would have bought that a LONG LONG time ago in fact, if that were true, I'd put a hold on the VT2 and get the stroker instead LOL.

Crap you're probably right. I have no idea, I'm probably interpreting it wrong. I've never gotten a Dinan mod which requires a core exchange. Will need someone else to chime in here. Or I guess I could call Dinan tomorrow and ask...haha
If that's the case, then I guess you're paying the extra $$$ for the warranty and trust that Dinan rebuilt their diffs well.

Yeah, it's kinda confusing. Maybe I'll call too just to double check if I'm missing out on the stroker here.
Nope it is $2999 plus the core exchange on top, I even spoke to Dinan about it last week. Randy I may either go your route which is find a reputable shop and just purchase the parts and have them do it or go another route which I am still contemplating.

Ah, thanks for clearing that up. They need to improve the wording on their website.

Why Dinan 3.91 Diff Vs. $700 ring and pinion?
Thank you for the help in advance guys.
in fact, if that were true, I'd put a hold on the VT2 and get the stroker instead LOL.
