Looks great Andy - what size are the rear bars?

Brake wise, as I recall, you are using 304 vented discs front and rear, with AP 4-pots up front and HiSpec 2-pot rears? I can't remember the piston diameter of the rear calipers? I think I am right in saying that you've got an adjustable brake bias valve too?

Great that the new set up works so well! Would be great to measure the 60-0 braking distance

And the cornering is pretty flat (in fact, that looks really undramatic - but I am sure the G-force is there!)

Brilliant - any more pictures mate?

 

Rob, your are indeed right, i'm running 304mm vented discs all around with HiSpec callipers on the rear, with a bias valve fitted, the pistons are 38.6mm.

heres a few more pics and a short video, check out the TF behind in the first pic for comparison.

Nice video - looks as though you were caught in traffic a couple of times stuck behind MGBs! The G-meter I presume is calibrated at 1G per mark? In which case the cornering was indeed nice and flat!

BTW what app were you using to recording this? Harry's Lap timer permits you to connect up to the EOBD connector to get engine rpm data from the ECU

 

Rob the front and rear bars are the same.. Made 80% stiffer than stock F ..

Double shear drop link mount s front and rear.. Rose joint drop links front.. Bespoke Kedunga mounts rear..

Andy.. Looks good now.. Suspension should be doing the work to keep the tyres on the ground.. And it can now the body roll has gone..

How ya finding the Torsen diff out of the corners..?

No probs with brake fade or heat then?

The diff is a quaife and definitely felt that I had more traction in the corners and able to accelerate out a lot quicker.

No brake fade at all and heat not an issue. Also contrary to whats been said in previous threads the back of the car didn't spin out when braking, not sure what would have happened if I hadn't had a bias valve.

 

I was using a Road hawk Camera with GPS and then running it through Race Render 2 for Mac.

 

I have some research to do then! thanks Andy!

Allan - same thickness bars front and rear? Interesting! Are they adjustable chaps?

 

what side intakes are those?

 

The Mike Satur F-One, now being sold by Motobuild.

 

My bad..,thought you had a type A or B Torsen diff..

 

Using the VHS thicker anti roll bars for road use has certainly helped the handling of my car too. I sped around a local roundabout leaving a Golf GTi way behind last weekend.

He could have been a crappy driver of course, but the TF really took the corners well. I was impressed with the difference from standard...

 

Great photos and video Andy!

It was my first track day yesterday and I really enjoyed it. I suspect my Steppie was frowned upon by some (at least one B owner expressed surprise I even bothered) but I kept up with many and was only overtaken by the highly modified cars in my group. One thing about a Steppie...you're always in the right gear at the corners! :lol:

Good to meet you yesterday. Who was that with you, I didn't catch his name?

Enjoyed the day so much I booked a repeat in September this morning!

Really nice to meet you to, its always good to put a face to people. That was Clive i was with, he posts on here as TF54CMF.

 

Rob the stock F and TF had same thickness bars front and rear from factory..?

The 85th had thicker front bars than rear for some reason..

Think (someone correct me) the Trophy had standard ARBs front and rear

I did ask Darren what thickness his are on his super sport but never got a reply

Panthers were standard... Cheetahs ? Anyone?

I did look at having adjustment on the bars.. But opted for an exact copy of factory just 80% thicker..

 

No, there has always been a difference in the diameter of the front and rear bars on the MGF and TF.

ARB diameters (in mm) for front (F) and rear (R)

MGF (including Trophy) - F: 19, R: 17
TF (2002-2005) - F: 20, R: 18
TF (MY2005) - F: 21, R: 19
TF 85LE - F: 25, R: 20
TF VHS handling kit - F: 25, R: 20

Going 23mm front and rear is pretty radical compared to the norm - and am interested to hear Andy's driving impressions?

Note that diameter is not the sole variable at play here - the TF rear ARB is very different with a longer lever distance to the pivot centre of the ARB compared to the MGF - and therefore "softer" than its diameter may imply if the ARB were made of the same material. I do not know the specification of the steels used in the above ARB designs.

I've got a set of TF ARBs sitting in the garage (for, errr, 10 years) to play with on the F - but ultimately, the F will be converted to TF suspension using VHS ARBs.

Andy Watson/ Diesel D - F: 22.8, R: 22.8 ?

I sent Coil Springs UK the stock ARBs from an F and asked for 20% thicker than stock

I never measured the new bars.. just assumed (wrongly) that both were 22.8mm.. guessing they made both bars at 22.8mm

Trouble is we have both wrapped the bars with silicone tape..

I'll measure my rear tonight with a Vernier

They certainly both look identical

My bad

 

Ah.. sorry Rob

In that case.. each bar is 80% stiffer then original..

They (coilsprings UK) copied each bar exactly making it 20% thicker..

So fronts are thicker than rear..?

:minxy:

 

The 85th kit used double shear drop link mounts on the fronts.. but not sure about the rear? Anyone?

I was advised by guru Pitka to double shear both ends..

 

Double shear on the front, standard on the back i think Allan.

 

The measurements will be interesting Allan, thanks!

Are 85LE front drop links double shear? I thought they were similar to the ones used by Toyota on the Camry model (and appear single shear to me)

 

The 85th used a bracket to pick up the other side of the drop link on the wishbone..

 

Gotcha - me understand now!

 

Its because the mounts on the wishbones are poop..

I opted for welding on a bit of flat bar and bracing for the double shear on my wish bones.. much stronger

 

The 85LE had this bracket beefed up, and unsurprisingly, the VHS uprated ARB kit is similarly specified.

 

Yes, I think you're right there...

Allan, did you get to measure the diameter of your rear ARB?

 

Sorry Rob.. Will do it tonight

Double shear rear links on the TF would be tricky.. Easy on the F though

 

I don't think the front was double shear? Unless I'm getting mixed up with what double shear means?

The bracket was beefed up and that was it? Oh and the better drop link

 

85th front is double shear on wishbone John..

The bracket mounts so that both sides of the drop link are picked up

 

That's not the way mg did it though?

 

 

Good pic John..

I could of sworn if seen a pic with that bracket fitted so it was double shear..

That's the way they should of done it!

 

Tbh if you've managed to fit it so it double shears, I'd go with your way
