1.6 springs fit a FR150 diesel?

Hi. got a mk1 leon fr tdi and ive just brought some weitec 40mm springs for it. got them very cheap but there off a 1.6-1.8. does any no if they'll fit????? thanx

it's not so much the fit of the springs I would be concerned about, but more the spring tolerances. Diesels are MUCH heavier over the front axle and probably require a stronger front spring. Don't take this as gospel, but I would imagine this to be the case.

weitec do supply different lowering kits for the 1.9tdi and the 1.6 so i'd suggest different spring tensions. i'd imagine it would sit lower, and perhaps handle differently due to the mis match.

I'm no suspension expert so I am loathed to give too much advise, but I would imagine:

1) The car could sit unevenly on the springs

2) This could unsettle the car under cornering or heavy braking

3) The damper & spring stroke will be mismatched therefore causing a very unwieldy ride quality

Personally I wouldn't recommend it at all, but maybe speak to Damien at DPM on this forum as he sells Weitec.

Looking on the weitec website they probably won't fit your car. If they are off a 1.6 no chance. If they are off a 1.8 they may but as you describe them as from 1.6-1.8 unless they still have a part number I'd sell them on.

You engine hangs lower than a petrol anyway and all that weight on weaker springs will just make it bottom out and the sump catch.

Fitting is one thing, the way they perform is something else. I could squeeze into a large ladies swim suit but that doesn't mean I can qualify for Miss World!

Best of luck mate I hope that all is OK with them and you're safe if nothing else.

:lol: we definitely need some pics of that in the SCN calender :lol:

After buying TA Technics coil overs for our oiler, I've ended up changing the front spings twice! They come with approximately 320lb main sping with a free length of 6" plus a 4" 'helper' spring which is very soft. I found the car too harsh & thought that the main springs were too stiff, so I bought some 225lb springs (full tarmac spec rally Escorts run 200lb front springs). FORGET IT, I got it totally wrong! The ride was now totally unacceptable - quite surprised something didn't break or bend! The problem I was having with both the original & second lot of main springs was that they were binding - i.e. not enough travel & with the 225's being softer they bottomed easier! The problem was that the useless helper springs were taking up to much of the travel, so I've now bought some 10" - 275lb springs & done away wth the helpers, result is a transformation! The car now goes over bumps & doesn't try to go through them! I think I could have had 300lbs but am happy with the 275's for the time being. I think the original set up was desigend for petrol engined Leons - not suitable for the heavy oil motor!
Not exactly an answer to your question but possibly some insight to the petrol/diesel comparison. By the way, the TA Technics coil overs are great!

This is a very bad idea, a cars springs are rated for a certain load and designed to carry that load with specific characteristics, if you install a spring that is under rated you will get problems under braking, acceleration and going round corners, eventually the spring will break which isnt that serious. its only when your going round bends quickly and it starts acting all odd and you end up in a ditch you will see the error of your ways....

Don't entirely agree with you there Jay, wouldn't say that it was as dangerous as you are implying. I did ask on here a while back if anyone knew the standard factory spring rates but had no replies. Quite simple - if they're too soft, the car will bottom out/coil bind severely to the extent of a serious lack of ground clearance (could bash the sump), cornering would also be interesting as the suspension would have no or very little travel, as I experienced with too soft a spring & not enough travel, the bottoming out is bloody harsh & extremely uncomfortable. In this case, if they were to be too hard (doubtful) you'll get loads of ground clearance & the ride would be stiffer but possibly not mega harsh as you'd have no coil binding - as I said, I doubt very much if a petrol engined car has stiffer spring than a diesel.
Put them on a scales, squash them an inch & take a reading - not hugely accurate but it will give you some idea! I used our pallet weigher & the fork lift with a pallet of good on it to sqeeze the spring!!!!
Surely springs aren't that expensive - just buy new ones!!!
