what`s the best springs to use on the yrv turbo looked at a few but all state 25mm drop,is there a spring with more drop or is 25mm the norm,keeping the car on 15" rims but want to take up the gap,any ideas

Don't really grasp your meaning of 'taking up the gap'. If you want your speedo to read correctly, the rolling radius of your tyres must be the same whatever size rim you choose to use, therefore your ride height would also be the same.
Before you look at shorter (and presumably stiffer) springs, get under your car to see what unloaded clearance there is for spring compression before the rubber snubbers bottom. Some of the pics on this forum show about an inch with the shorter springs fitted. Not very good for rear seat passengers. If the suspension bottoms on the snubbers it hurts and if the springs are stiff enough to prevent bottoming then it will hurt less but all the time!
The YRV front suspension is very hard anyway and my advice would be to have special stiffer rear springs wound to retain the standard unloaded ride height. Bob Fudge (BobF)on the forum knows who to go to for that.

It occured to me that I hadn't been too clear above.
Underlying my point was that (in my view) modifications to cars should have a particular need. Usually the 'need' for shorter springs would be that they would be stiffer, thus limiting cornering roll.
In the case of the standard YRV the front suspension is too hard and the rear too soft. Thus by changing to stiffer springs at the rear you would improve the front/rear balance of the suspension and limit cornering roll. Those stiffer rear springs would need to be designed to give the same static length, to maintain the car's attitude. By taking this approach you would avoid potential problems with wheelarch and suspension clearances.

Hiya Mate. Know what you

Know what you mean with the YRV, and I too looked for ways to accomplish what you want to do. In the end I got lucky and found a set of Tein springs for sale @ japaneazi.co.uk and these lower the car by 30mm front and 35 mm back. Also I went with wider ET35 alloys and 195/50/R15 with HRT 5mm wheell spacers tyres to fill the arches. I have posted up many a photo of the mods I have done to my yellow YRV turbo under the gallery sections of Cars and Modifications if you want to get an idea at the final product. The result, well the bottoms as described kept rubbing the rear arches and gave a really bouncy feel on the back, on the plus side I can now go around corners a lot better. My latest modification is a couple of one off adjustable rear dampers (AVO) which helps with the wheel arch rubbing. My only options now are to either remove the rear spacers and grind down the rear axle to get the tyre to pass, or a different tyre brand which doesn't come out as much to moving to 185/50/R15 tyres
If you need more details on what I have done and lessons learnt send us a private message and I'll get back to you
