  1. ..10 years ago (- 1 1/2 moths) I tool delivery of a work in progress 4a from TRGB and tomorrow my car goes to a good friend of mine, who will give it the time and enthusiasm I'm not doing at the moment.  I will fortunately (I hope..) keep the opportunity to now be the co-driver to my friend who's been my co-driver on 4 Classic Le Mans trips and a few UK tours too.

    Just wanted to acknowledge this forum and the individuals that have helped me over the years, so thank you one and all and I wish you safe TRavels..

    From me and my 4a.. Ta Ta

    Standard design by Triumph, understeer is safer than oversteer, that's what the the standard fitment front anti roll bar with no anti roll bar at the rear gives you, less roll and masses of understeer. If owners have never experienced understeer in a front anti roll bar car only car...then you are not driving fast enough !

    It was a combination of steering wheel play, body roll, lack of brakes plus masses of understeer and tyre roll!

    Thanks everyone for the advise. I’m still deliberating and thinking perhaps I will contact Phoenix directly for a chat.
     

    I have memories of my father driving to work with an a custom exhaust from Mike the Pipe many years ago!  I could hear the car for miles! I like the idea of a sportier sound without being overly intrusive. I will let you all know how I get on.

    Full Phoenix system with manifold and single rear silencer - sounds great and suits the car perfectly for me.

    Yes, I have a set in my 4a and have done for quite a while now.

    I recall my first drive with these and the engine pickup was noticeably quicker, a bit like taking weight off the flywheel.

    Recommended by me that's for sure!

    Thanks Mark, from the front view you have posted, my wires are more offset, at least 1" I'd say.

    It only just catches the lip on the arch..and only on the odd occasion..will probably drop to 165's when these tyres are done (in 15 years or so)

    Will slow you down in the corners for sure...  I'd have the wheels changed personally.

  6. Thinking about it I'm pretty happy with the ride height as there's reasonable compliance when driving and if I do hit a bump mid-corner the car isn't upset - just absorbs it and carries on.  The tyre wall obviously helps too as does keeping correct tyre pressures.

    General ground clearance is OK with the silencer as mentioned being the low point.  I have hit the front pan a few times when in a dip at speed, but then again that was probably preceded or followed by another bit of the undercarriage connecting with the highway too.

    Hi Stuart

    5.5 wires, with 185's as mentioned, the wires aren't centre laced so have a bit more offset.

    PO fitted uprated front springs, that sit the car an inch or so lower than std. There is 1 1/2" from arch to tyre looking side in. The back looks about the same as Marks, but front is about an inch lower.

    Doesn't happen all the time, only bumpy sharper corners..

    I have the original springs in the garage.

    Just thought 165s might give a little more clearance

    Mine's got lowered stiffer springs and I really wouldn't want to be any closer to the deck than this as keeping the silencer off the tarmac would be an issue.  An inch or so less on the front would for me prove problematic I think.

    I'll post a front view too to see if that demonstrates what I mean better

    Could you tell me where you got your mirrors and if possible the model. Do they work well and do you have flat or convex glass? Sorry for so many questions

    Andy

    No trouble Andy.

    I think TRGB but then again I get all of my TR stuff from there.

    To be honest I mounted them in a more easily accessible place to drill the door so I didn't have to disassemble the door.  They're fine really and tend to keep the passenger side so the passenger has a rear view leaving me the drivers side and rear view.

    Glass is flat - the curved glass gives a really odd reflection that I'd prefer not to have.

    Nice, like the shape of the door mirrors too..

    Can I ask what size tyres you have fitted.? .Im finding the 185's on my 4 are just catching the wheel arch lips on the fronts on a bumpy road..

    Nigel H

    185 65's.  I'm quite low as you can see in the pic' but no rubbing and plenty of thrashing about on bumpy roads too.

    The Phoenix systems seem very  popular (but pricey). What's the noise level like at cruising speed (say 60 -70) with the big bore sports system?

    I've not managed to find anything of the same dimensions as my current back box, so I might have to bite the bullet and replace the complete system. I know it's probably been covered before, but are there many advantages of a big bore system over standard bore on a standard engine ? And what size is standard bore anyway?

    Thanks, Brian

    Depending on how buried my right foot is it's either the twin Webers or the Phoenix I hear the most, but typically is a combination of them both.

    The full system sounds great!

    Thanks Mark. What bore is the inlet pipe?

     

    Good question Brian, but I don't know and the car's not here for me to measure.  It's the Big Bore sports system & sounds great!

    I have ground it a few times when on tour, loaded up with co driver and not sparing the ponies...  If you tuck it up out the way neatly you have to try to ground it.

    I don't think mine's as upswept as Stuart's but I'll look for a side shot.

    I'd highly recommend the whole Phoenix system.

  12. If you have the opportunity to, do check the actual liners are within spec height wise too.  My rebuilt engine had a very slight yet persistent water loss issue that was traced to one of the liners being shorter than the other three.
