    Re: Steel bubble arch & tub fitting

    I would say that before you start doing something like this you ought to try and estimate the costs/time/effort etc...

    I know exactly how much Gartrac charge and it includes the price of the arches...1200.

    It involves cutting great areas of the rears out and if done wrongly could be disasterous...I will try and post my pics from Gartrac when i am at home.

    Re: Steel bubble arch & tub fitting

    Is it that much harder than doing the bubbles alone? To be honest it doesn't look all that difficult but then I have never attempted it. Certainly cannot afford for somebody else to do it for me.

    Gary (Retromotorsport) has posted that I should do it as security. Guess he has done a million tho and knows what he is doing!

    Re: Steel bubble arch & tub fitting

    I am not at all phased but fitting the bubbles themselves but it is the large tubs that worry me. It involves cutting away some of the panelwork/framework that sits on top of the existing standard tub. Seems to me that I would be weakening the structure of the car but Ive seen a million pics of them done (especially by Retromotorsport) that dont appear to add any additional bracing.

    Must be ok........deep breath then cut cut cut weld weld weld

    hi all, i know this is a late post but all this talk of steel bubble arches costing over a grand is a rip off, look on express steel they sell them for 92 per arch

    The arches cost around 450, and i charge 350 to fit them , this is on a shell thats allready half tubbed or full tubbed,
    theres also the option that i do for larger diameter wheels and different front end geometries to enable 10" wide front wheels to be used, which involves a subtle re shaping of the front arches.

    My Larger than Gp4 rally tubs , more like the Gp4/5/6 tubs used by Zakspeed etc on the tarmac cars, these along with the revised turret position i do allow 12" rears to be comfortably swallowed under standard tramac Gp4 arches are 800 fitted, with the turrets being 270 with free Chassis Notching* for TS subscribers ..

    *the Road/Race chassis notch is a done to a greater clearence than the Gp4 Rally car little chassis raise

    Re: Steel bubble arch & tub fitting

    Tom,

    Have you ever fitted any?

    From what you are saying...you obviously think the added cost is too much for someone to charge what I think is a reasonable amount to do a great job and not write your car off in the process.

    I reckon I could build an engine out of the best parts available...not sure it would run for long...if at all.

    As someone who has seen this job done both very well and terribly...I reckon that 200 per corner is quite a fair amount.

    Russ.

    Re: Steel bubble arch & tub fitting

    and if you saw how long it took me to fit mine and hopefully have got it right, 350 is buttons to have them done by someone who actually knows what he is doing.

    I agree thats cheap. I paid the equivalent of 900 Pounds to have fibreglass ones fitted and that was me supplying the guards!

    Re: Steel bubble arch & tub fitting

    Russ's price of 200 / corner is incorrect, in a way, as i belive that's including the inners at the rear , 350-400 to fit the arches and 400-450 to do the inners ..

    Re: Steel bubble arch & tub fitting

    As you know I had mine done at Gartrac.....they quote 1200...that includes the arches which are top quality...you should feel the return on them....that includes all the rear tubbing...

    That price is + VAT I think...

    For me...they were great to deal with and turned out a great job...

    The car is what I have always wanted and I did not want to risk botching it up......go to an expert such as Gary or Gartrac...

    Regards,

    Russ.
