Here is a pic of the area that needs to be milled down. Its obvious this is a new peice that Hyperdrive made themselves as it is different in design than the 12R5 front mounts. when they designed it for some reason they made the arms quite tall.

I'm guessing that because HD is more of a 1/10 oval company thay made the height to fit their 1/10 pro4 car.

I did some weight comparisons on the steel hardware on the R5 front end vs alloy/Ti screws.

All the steel bits together per side weigh in at 5+gm's

Replacing them all with Alloy/Ti = 1gm

So if you replace most of the screws with alloy ot Ti, the R5 front end is only like a 2gm weight penalty over the stock L4 front end.

I think the plastics on the R5 front end are far superior to the IRS or the AE hardware. Much more exact and refined pieces.

But with that said, the L4 front end is back on the car until I can get a shop to mill down the HD blocks. I did also send them an email and ask if they would consider releasing lowered blocks. I did add up how much this front end costs. I ordered all the parts seperate, because I didnt want to order the AE alloy block in the full front end kit. I got all the R5 plastic, and steel hardware, HyperDrive lower block, Hyperdrive lower arm inserts, and HyperDrive teflon coated balls for ~$100... so I am not so sure it was worth it in the end. I think it will be easier to adjust and easier to keep trued up, but not that much better than the L4 front end.

So how small of a tire can you run at 3mm ride hight ?

$100 ??? Would have been better to buy the kit for $60. Im sure some one would buy the stock plates so you could recoup some of your cash.

Could probably get the tires down to 1.60 on the front and stay at 3mm. But thats real close, and w/ droop you'd be below 3mm

Yeh $100.00 The HD blocks alone cost $20.00, The mounting inserts were $11.95, and the teflon pivot balls were $16. so just with those 3 parts I am at: $48.00, The rest was just he plastic, screws, and the Ti Axels and the center CF brace. so instead of spending $60.00 - 65.00 on the full front end kit (which is sold out everywhere and I wouldnt have been able to get it in anytime soon), and then spending another ~$50. I spent around $100 and got it all in hand in 2 days.

Ya, thats way too high. I can run 1.55 tire at 3.5mm ride height with a .5mm shim under the front bulkhead on my R5.

Yeh I did some measuring again, and think I could get it to 1.60 in absolute best case scenario... but that is riding on the chassis and that doesnt work.

Does the Black Mamba work on the 1/12 BMI? I wonder if there's the same problem as with the Hyperdrive? Thanks.

According to this post it fits, but I've never seen it in hand myself and at $119 for the complete kit its not cheap.

Most likely for the 1/10 oval cars with the larger tires.

Just heard from HyperDrive... they have some that are at stock 12r5 height. They are going to get me the part number tomorrow, I am going to see about returning the ones I have back to Lefthander to get the right ones.

They are too tall for 1/12th right now. I e-mailed them and talked a bit...they do have a 1/12th version in the works.

The DB12RR LiPo worked great for me this past week at the IIC. I just wish the driver was as capable as the car was
