Re: Grand Vitara on steroids | 2" lift kit, rear LSD & more BHPians Thank you for your kind comments. Regarding snow chains, as 245/75r16 tyres have been installed, the two inch lift kit would have taken care of that but a very small clearance especially at the lower wheel arch was left and there was a bit of rubbing on full steering lock. To compensate for that, wheel arches have been widened besides steel wheels with negative offset were chosen, the tyres were out of the body by almost an inch and a half. This is the reason wheel arches were modified to provide extra room for articulation and space for snow chains if needed.
Grand Vitara has a full time 4WD system with a proper low range gearbox. "4H lock" position locks the center differential, which means that equal torque is sent to the front and rear differentials. The front and rear differentials do NOT lock, so individual wheels may still slip.
4L Lock is gonna keep the differential locked, but also engage a reduction gear in the transfer case so the effective gearing to the wheels is much lower through the gear range.
With larger tyres there is between 3-5% speedo difference but with such mods the focus was not to build a race track car, its an adventure vehicle, it will go slow but has the goods to deliver in demanding situations. It does feel a bit sluggish on road but when it comes to mud trails, the low range comes in handy and provides the extra boost that is required for such situations and it is pretty adequate. I recently was following a gypsy on a mud trail, GV did everything gypsy was able to do and it did it even better by being composed due to independent suspension, if you know what I mean! GV offers un-comparable comfort as opposed to a gypsy on any terrain and with all the electronic traction control and full time 4WD, GV has proved better. Certainly, Gypsy is a bare bone hard core off-roader and it can take a lot more beating than a GV, but I have no intention of pushing GV to that zone. In coming months I shall put GV to paces and shall share photos and videos of how it does in various off-road situations.
Also there was a query asking for the reason going for LSD instead of air locker, LSD engages and disengages on it own based on the wheel spin and provides 90% of the engagement, on the other hand, air lockers offers 100% engagement however one has to plan , stop, turn them on and off before attempting a trail. Considering what GV is capable off-road I felt LSD more practical as it works without any additional input.
I have tried responding to all the queries that have been raised on the above posts in one answer. Please feel free to comment and I'm open for suggestions if any. |
