Yokomo BD7/BD8

[Lee24h]

I thought I would inject a bit of life into this c'mon lets talk touring cars and see those cars as well :woot:

[Scotty83]

I agree Lee. Not enough TC talk on here. I want to get a bd8 soon as still got the 15. Haven't seen many about tho
What do you have?.

[Lee24h]

Ive got a bd7 16 but will be getting a bd8 if I get a bonus at work

[Plasmag]

Hi Lee do you run your BD7 on carpet? as have been trying one on low to medium grip carpet and cannot get a good set up. The back end of the car looses grip in an almost slow motion fashion. Have tried softening the car and high and low roll centres but have not got a decent set up on low to mid grip carpet, car is great in high grip. Any tips?

[Lee24h]

Have you tried a stronger front anti roll bar and actually running a higher roll centre at the rear and shortening the camber links all round

[Plasmag]

Not tried a stronger front arb will have a go but tried everything else coming to the conclusion its for high grip tracks only ( not much chassis roll due to being all low porofile).

[Lee24h]

Its trial and error there are a few setups that work but its all about
The thing is on the yokomo small changes make a massive difference i also find harder springs can work in low grip as it generates more heat in the tyres quicker

[Plasmag]

Thanks Lee

[Scotty83]

Has anyone found any shock orings/ seals that don't leak

The BD7 & BD8 are both great Touring Cars!

I've had the BD7 13, 14, 15 & 16 & only ever used them on Carpet.

When you talk to fellow Racers, there always seems to be mixed Opinions on which felt Best & Generated the most Grip.............personally, I found my BD7 '16' to be Best Car!

Generally, I ran mine on the Lower Grip Grey Prima Carpet & it seemed to go well & give decent Grip, but I went down a slightly different route on Setup, from the usual you see on Petit, as those are really for the High Grip Black ETS Carpet!

I've since Bought the New BD8 & I have to say, Yokomo have vastly Improved the Car in most areas!

[Lee24h]

I cant wait to one day own a bd8 but yeah its always mixed
opinions when it comes to the bd7

[Scotty83]

Has anyone got a set up for ets carpet on a tight track

[john wolfe]

Change the liquid u put on rear tyres for more or less grip and a really hard spring with a 250cst shock oil ive run my bd7 at leam car club and its fine

From or rear spring harder? Need more rear grip.

[Wacker1]

Scotty83, what Setup are you currently on with you're BD7?

[Paulpdm]

Does anyone have a good set-up they can share for the BD7 16, for indoors, small, tight and twisty track on prima felt carpet?

Thanks!
Paul

Scotty83, what Setup are you currently on with you're BD7?

I run my bd7 on ets carpet with ally chassis shocks are the slt shorter shocks with blue springs front rear is white springs yellow there hard with carpet addative green spider slime on rear front any good addtive will do and what the club allows shocks r mounted at the lowist point on towers 250cst shock oil short camber links all round i take it ur using soft carpet tyres yes. And rear chassis weights 30g each side turn ur punch down on hand set and make sure the belts are not to lose but not tight or they will snap hope this helps u abit mate

can anyone tell me the difference with a standard and a black series?

I'm looking to get one, but not sure the difference?

Ideally I'm looking at 2015 or 2016

Have a look at the upgrade kit at £279 on mb models and wheelspin models for 2015/16 ive got a 2014 up graded to a 2015 and its ace bit of kit but then it should be at that price

The BD7 '13' only came as a Blue Anodised Kit, but the BD7 '14' gave you the Option of 'Std' & 'Black Series' Kit..........Std meant Blue Anodising throughout & Black Series meant Black/Silver Chamfered Anodising throughout!
Other than the Colour difference, both Kits were the same Spec though.

Whereas, the BD7 '15' & '16' were only Available in a Black Series model.

Personally, I'd go for a '16', as its better for Carpet & also gives you the Option of Upgrading it to a BD8, with the Conversion Kit that Yokomo currently Offers.........the BD8 is also a better Car!

The reason i brought a bd7 16 was so i had two cars with similar parts when I buy a bd8

[Scotty83]

Scotty83, what Setup are you currently on with you're BD7?

Blue and pink springs. 400 front 450 rear. 5.2 ride height. 5.2 and 5.8 droop 4 diff oil

[Wacker1]

Blue and pink springs. 400 front 450 rear. 5.2 ride height. 5.2 and 5.8 droop 4 diff oil

With that current Setup, how does you're Car feel?

.i.e what do you feel that you're lacking?

Are you running the Std Length Shocks or the Slim Short Shocks?

[john wolfe]

Check out mb models and cml uk both list the upgrades that you get and shows the differnce for each model

Standard shocks. It lacked rear grip. No confidence in the car going into corners

I'd go with the Following mate :

FRONT
44.2 FF Block
44.2 FR Block
450 Oil/1.1 Piston/2 'O' Ring/25% Rebound
Blue Spring
Hole 2 on Tower
Short Link/1mm Inner Shim/1mm Outer Shim
2 Degree Camber
5.5 Droop
1mm Bumpsteer Shim
0.5mm Steering Shim
Spool
1.3 Rollbar

REAR
42.0 RF Block
46.4 RR Block
450 Oil/1.1 Piston/2 'O' Ring/25% Rebound
Blue Spring
Hole 2 on Tower
Short Link/1mm Inner Shim/1mm Outer Shim
2 Degree Camber
4.5 Droop
2k Diff Oil
1.2 Rollbar
Motormount screw out if using the Aluminium Chassis

That should be a pretty Safe Setup thats nice to drive, but if you find that you have too much Steering, you could switch to either a 1.4 Front Rollbar, take the the 0.5mm Shim out of the Steering or go to 3k Diff Oil.

If you find that you require alittle more Steering/Response, then you could go to Hole 3 allround on the Towers or go to Pink Springs allround.

Hope this helps.

I will try that. What ball joints do you use. Black or silver

[Wacker1]

I will try that. What ball joints do you use. Black or silver

Use the Std Silver Ballstuds with 1mm Shims, on the Inner Bulkheads.

If you feel that you require alittle more Grip, you could always Remove the 1mm Shims from the Inner Bulkheads.

The Black Ballstuds have a shorter neck, which is 1.5mm lower..........I've found if you run it like that or even lower, all it does is scrub Cornerspeed & create more Tyre Wear!

As you're Car sounds like its a BD7 - pre 2016, I'd also run the Spool & Diff in the Low Position.
..........with a 2016, you'd generally run them both in the High Position.

[Scotty83]

Yes it is the 15.

When you say have diff and spool in the lowest position but then adjust it from there depending on the tight Ness of the belt.

You mention about the engine mount bolts. There are only 4 on there. Surely it would come loose if you took bolts out

Yes, you keep the 4 Countersunk screws in, that Attach the Motormount to the Chassis, but if you're running an Aluminium Chassis, you leave out the top Button screw, that Attaches the Motormount to the Top Deck.

[Scotty83]

Oh yes. Sorry I get you know. Yes I have that out already.

Yes, Spool & Diff in Lowest Position, then just tweak the Cams for the right Belt Tension.
I think the 'Kit' Setting on the BD7 '15', was Low Position anyway, but the Front Belt may need to be one notch tighter than what the Manual said.

With the Motormount/Top Deck screw out, the Car will generally have more allround Grip & Steering, but you do Sacrifice abit of Rear Traction.........Standing the Rear Shocks up one hole, helps with that though, if you feel that you need more!

[Scotty83]

One question I do have. Anti roll bar link mounts. Is there a safe position to start with as you can mount near the end of the anti roll bar or you can move it inwards. Is it better to have them upright or at an angle?

To be honest, I've never Experimented with the Angle of the Antiroll Bar uprights, I've always ran mine so the Uprights are perfectly Vertical, which leaves around 5mm or so, of the Bar exposed.

[Scotty83]

This is something I have tried and it does make a difference to how the car feels.

[Lee24h]

Short shocks 450 all round and pink fromt springs and blue rears and 850 in the diff
